Abstract :
The advantages of using a time division duplex-code division multiple access (TDD-CDMA) air interface for mobile multimedia services are presented, with reference to an equivalent frequency division duplex (FDD) CDMA system. In particular the flexibility and limitations of using an asymmetric channel are discussed. It is concluded that TDD-CDMA is ideally suited to short range high bit rate asymmetric services, whereas FDD-CDMA is better suited to large cells using symmetric channels
