Analog vs. Digital

• ANALOG
• The human voice is analog
• Characterized by complex and rapidly changing
  waveforms

• DIGITAL
• Digital is simply a series of 0s and 1s (on and
  off, etc).
• Analog waveforms can be converted to/from digital
  form
• Some intelligence may be lost in A-D / D-A
  conversion

6
Interoperability

• Analog interoperability primarily requires using
  the same frequency.
• Digital interoperability requires use of similar
  technologies and identical data formats.
• Unless built to a common standard, digital radios
  are unable to communicate in a digital mode.

Positive Experiences

• Digital range is indeed comparable or superior to
  analog.
• It is easy to achieve 12.5 kHz bandwidth with
  digital and virtually impossible to reach 6.25
  kHz bandwidth using analog FM.
• Encryption is essentially a byproduct of digital.
  A much higher degree of security is possible
  with digital.
• Interface with other digital devices is
  facilitated.

23
Negative Experiences

• Initial cost is higher for digital.
• Although designed for backward compatibility to
  analog, use of analog results in loss of many
  digital features.
• Base station range may be reduced in simulcast
  mode (a result of applying the laws of physics).
• While usable range is at least as good as analog,
  digital gives little notice as the edge of the
  service area is approached. Once bit error rates
  exceed acceptable tolerances, reception abruptly
  ceases.
• Vocoder noise overload degrades quality.

Steering Committee Actions

• Discussion on Phase II TDMA began in earnest in
  2005.
• In 2006, the P25 Steering Committee took several
  actions to facilitate the development of TDMA
  standards for Project 25 Phase 2
• Two important motions were passed by the Steering
  Committee
• Half-Rate Vocoder Motion January, 2006
• Phase II TDMA Motion October, 2006

38
½ Rate Vocoder MotionMesa January 2006

• The Steering Committee hereby states that it is
  willing to support use of the enhanced half-rate
  IMBE vocoder as outlined in the Vocoder Task
  Group report when it is part of a harmonized
  2-slot TDMA in 12.5 kHz bandwidth and/or 4-slot
  TDMA in 25 kHz bandwidth proposal for Phase II
  that is capable of providing voice quality, radio
  coverage, and other performance that is
  comparable to that provided by a Project 25 Phase
  I system.

39
Vocoder Testing Results

• The Enhanced Vocoder (Full Rate or ½ Rate)
  clearly outperforms the original Project 25 IMBE
  vocoder.
• The Project 25 Steering Committee recommends
  that, effective immediately, all agencies require
  the Enhanced Vocoder in all Project 25
  procurements.

Phase 2 TDMA MotionMinneapolis Oct 2006

• The Steering Committee will not consider any
  action on Steering Committee acceptance of a
  Phase 2, TDMA solution at this meeting. This
  reflects the progress that has been made on a
  preliminary design through the TDMA working
  group.
• The Steering Committee expects, however, a design
  agreement, a technical design solution, a
  documentation plan, and proposed schedule to be
  presented at the January 2007 meeting in Mesa,
  Arizona. The Steering Committee will not
  consider further extensions to acceptance of a
  Phase 2, TDMA direction from the TDMA Working
  Group past the January 2007 meeting.

43

  unable to reach full consensus as evidenced in
  the polls taken on April 19 (conf call) and April
  24 (Dallas Meeting) and thus understand the issue

07-012 - TDMA - (SC) Phase 2 Motion to Proceed
44
Steering Committee Action Dallas April 2007

• The issue of proposal selection (9.6 vs 12 kb/s)
  is referred to the Steering Committee
• For the 12 kb/s harmonization supporters to be
  able to proceed on a Phase 2 TDMA solution, the
  Steering Committee must consider the adoption of
  the enhanced ½ rate IMBE vocoder to support the
  TDMA Phase 2 effort.
• Gating item to design and documentation start
• The Steering Committee unanimously, with one
  abstention, approved the proposed harmonized
  design that follows, along with its associated
  documentation and timeline proposals.

45
Phase 2 TDMAHarmonized Design Overview
46
High Level Overview EADS, EF Johnson, M/A-COM

• We are convinced that the 12 kbps harmonized
  proposal is a solid design based on sound system
  design trade-offs and will carry P25 far into the
  future.
• We are concerned that a 9.6 kb/s data rate
  severely limits Phase 2 performance to less than
  Phase 1.
• The harmonized proposal allows 2.4 kb/s of
  signalling per user (vs 1.2 kb/s) which is the
  same as Phase 1. We feel this is a much better
  system design trade-off in the long run versus
  any alleged degradation in Simulcast coverage
  performance, especially given several techniques
  to resolve that problem.
• For a 9.6 kb/s Ph 2 standard, MAC layer protocol
  options are limited and it will be very difficult
  to change or enhance, limiting the ability to
  address future requirements.

47
1. Audio Quality

• The 3.6 kbps Enhanced Half-Rate (EHR) vocoder
  proven to exceed the Phase 1 Full Rate (FR)
  vocoder in voice quality
• Harmonized proposal PHY layer characteristics
  meet or exceed all Phase 1 PHY layer
  specifications
• 12 kbps allows for additional vocoder options
  such as adding more FEC to improve voice quality
  up to a total of 4.4 kbps
• 8-level modulation option for enhanced Simulcast
  can improve voice quality for delay spreads gt60
  usec

48
2. Access time

• Access times for the baseline harmonized proposal
  meet or exceed existing Phase 1 requirements
  without CC-TC synchronization
• Example
• Transmitter Time to Key on Traffic Channel
• Phase 1 150 msec average
• Phase 2 140 msec worst case
• The baseline harmonized proposal does not require
  Phase 1 FDMA control channel and Phase 2 TDMA
  traffic channel synchronization, but it does
  allow it for improved performance
• Other best case access time benchmarks from
  Phase 1 can be equaled or exceeded by
  synchronizing the FDMA CC and TDMA TC
• In some cases there is actually a TDMA penalty
  in access time due to having to wait for slot
  alignment on the traffic channel
• The baseline proposal can be modified to require
  Phase 1 CC and Phase 2 TDMA TC synchronization
  during migration to improve access times, but
  this may complicate migration for some
  manufacturers

49
3. Throughput Delay

• The harmonized proposal exceeds the Phase 1
  requirement
• Throughput delay through a simple repeater
  configuration
• Phase 1 350 msec
• Phase 2 baseline 260 msec
• This specification is also known as latency and
  is related to audio clearance/audio buffering
  delay
• It is our experience that differences in audio
  clearance/buffering due to factors like slot
  size, or bi-directional signalling capability,
  are typically close to an order of magnitude
  lower than throughput delay/latency as is usually
  seen in deployed systems and networks
• Thus, providing a feature like bi-directional
  signalling at the expense of some degradation in
  audio clearance/buffering was thought to be a
  better system design trade-off by the taskgroup

50
4. Sync Performance and Update Rate

• Frame Sync pattern number of bits is reduced from
  Phase 1 from 48 to 40 bits.
• Sync detector does not have to detect sync at
  random as in FDMA systems, but in specific
  windows set by TDMA slot times.
• Phase 1 sync was large to operate with FDMA
  channels.
• Phase 2 sync does not need 48 bits.
• However, sync update is greatly increased on the
  downlink for faster late entry.
• Phase 1 180 msec average
• Phase 2 60 msec average
• Faster update intervals permits faster sync on
  late entry

51
5. Sensitivity

• Phase 2 harmonized modulation easily meets Phase
  1 sensitivity requirements
• At least 2 dB of margin for worst case 10 dB
  Noise Figure in static and faded conditions
• H-CPM _at_ 12 kbps is more spectrally efficient than
  C4FM _at_ 9.6 kbps

More power in main channel
Less power in adjacent channel
52
6. Phase 1 Migration

• Phase 1 migration was a primary consideration in
  the development of the harmonized proposal
• The baseline harmonized proposal
• Specifies the use of the Phase 1 control channel
• But does not require CC/TC synchronization
• Does not require linear amplifiers in SUs
• Meets or exceeds Phase 1 PHY layer requirements
• Meets or exceeds Phase 1 MAC layer requirements
• Meets or exceeds Phase 1 Simulcast specs and some
  stretch goals
• Provides additional options for improved delay
  spread performance (H8PSK). Studies have also
  shown that in most cases a simple re-optimization
  of Simulcast timing can resolve coverage
  problems, if they actually exist, when migrating
  from Phase 1
• Provides bits for future growth
• Migration to Phase 2 requires linear amplifiers
  in the base stations

53
7. Encryption Late Entry Performance

• Encrypted Late Entry performance is predicted to
  be equal or better than Phase 1 under all
  conditions
• Encryption Sync Word, ESW, message probability of
  detection, Pd, at 5 BER faded is better than
  Phase 1 and uses a unique FEC decoding scheme to
  provide quicker late entry at low BER plus better
  message Pd at high BER
• Signalling rate summary
• The Phase 1 FDMA standard provides 7.2 kbps for
  the vocoder and 2.4 kbps for signalling (sync,
  NAC, LCW, ESW, status, LSD) per user
• The Phase 2 TDMA baseline harmonized proposal
  provides 3.6 kbps for the vocoder and 2.4 kbps
  for signalling (sync, ramp/guard, LCW, ESW) per
  user
• Other techniques are used for the NAC-equivalent
  and status bits

54
8. TDMA Control Channel Performance

• M/A-COM strongly believes that additional control
  channel capacity will be required for customers
  upgrading to TDMA.
• Users with large numbers of channels will not
  accept degradation in GOS when upgrading to TDMA
  and will likely require an increase in control
  channel capacity.
• The 12 kbps harmonized control channel will have
  significantly higher capacity than the Phase 1
  control channel in the same bandwidth.
• Estimated improvement
• 1.25X improvement in inbound CC capacity
• 1.25x improvement in outbound signalling
  bandwidth
• In addition, at 12 kbps there are sufficient bits
  available to provide
• Equal or better message Pd as Phase 1
• Possibly a more efficient (more capacity)
  message structure to reduce some multi-block
  Phase 1 messages to fewer blocks
• Time to Grant and Trunking Request Times are
  expected to improve

55
9. Co-channel behavior

• Meets or exceeds Phase 1
• In a co-channel interference context, 12 kb/s
  Phase 2 protects every single codeword with
  scrambling
• Avoid Phase 1 areas where interference cannot be
  easily detected
• Protection technique is nearly continuous and
  minimizes false detection of a co-channel
  interferer

56
10. Adjacent Channel Rejection Ratio

• Meets or exceeds Phase 1 performance requirements
• Estimates of Adjacent Channel Rejection
• 12 kbps H-CPM with 12 kbps H-CPM interferer 62
  dB
• 12 kbps H-CPM with 9.6 kbps C4FM interferer 63
  dB
• 12 kbps H-DQPSK with 12 kbps H-DQPSK interferer
  67 dB
• 12 kbps H-DQPSK with 9.6 kbps C4FM interferer 60
  dB

57
11. PA Efficiency (subscriber battery life)

• Same efficiency as Phase 1
• TDMA TG was very concerned with making the SU
  design for Phase 2 as simple as possible
• Therefore, the harmonized proposal specifies
• Constant envelope H-CPM on the uplink
• No linear amplifiers required in the SUs
• H-DQPSK on the downlink
• Easy demodulation in the SUs

58
12. Simulcast Delay Spread

• The harmonized proposal took into consideration
  the migration of all existing Phase 1 systems and
  was thus crafted to require a linear downlink
• The baseline harmonized proposal
• Far exceeds the Phase 1 C4FM delay spread
  requirement
• Meets the 60 usec, DAQ 3.4, stretch goal using
  the EHR vocoder
• Is close to the 95 usec, 5 BER, stretch goal and
  can meet it with a slight widening of the receive
  IF filter
• In addition, the H-D8PSK option provides delay
  spread tolerance far in excess of any currently
  deployed Phase 1 system
• Finally, studies have shown that in most cases a
  simple re-optimization of Simulcast timing can
  resolve coverage problems, if they actually
  exist, when migrating from Phase 1 LSM to Phase 2.
