Objectives

• In order to develop robust receiver-transmitter
  structures and algorithms suitable for future (4G
  and beyond) high-speed wireless communications
  JADE seeks to achieve the following goals
• Array processing
• To use space-time coding, array processing and
  differential redundancy concepts to exploit
  diversity and reuse the available radio
  resources.
• To evaluate the effect of radio channel and
  antenna design/correlation on system performance.
• To gain a deeper understanding on the
  achievable overall (link and network) performance
  in terms of BER, data throughput, coverage,
  capacity, and implementation complexity.
• Multi-user scenarios
• To assess the effects of interference from
  co-channel users (e.g., multiple access
  interference) on system performance as well as
  intersystem interference.
• To provide an explicit shift towards
  decentralized and adaptive MAC, RRM and routing
  approaches.

43
Objectives

• System integration
• To study the main signal processing and
  physical layer smart antenna techniques related
  to packet switching.
• To study and develop packet switching and
  scheduling schemes for the proposed context.
• To study the relevant interactions across
  layers.
• To propose novel link layer transmission
  techniques with enhanced frequency usage
  efficiency.
• Benefit from adaptive algorithms
• To compare performance and complexity between a
  proposed adaptive and fixed (non-adaptive)
  systems.
• To measure the impact of different variables
  (fixed or adaptively controlled) on system
  performance while keeping in mind implementation
  specifics.
• Sensitivity analysis
• To analyze the sensitivity of the algorithms to
  partial knowledge of channel state information.
• To assess the robustness of the proposed
  systems. Robustness here is measured in terms of
  dependence of performance on synchronization
  errors and channel estimation errors.
