Introduction

• Analog System
• Global System for Mobile communications (GSM) -
  1992
• Second Generation GSM (2G) - 1994
• General Packet Radio Service (GPRS) - 1999
• Third Generation (3G) - 2002
• Future Fourth Generation (4G)

4
Orthogonal Frequency Division Multiplexing, OFDM

• Multiple carrier modulation techniques

5
Application of OFDM

• Digital Video Broadcasting, DVB
• Wireless LAN
• Future mobile Communications

6
Contributions

• Better OFDM demodulation technique
• Better signal to noise ratio
• Reduced complexity of OFDM algorithm
• Reduce memory requirement in processor
• Reduce cost
