Frequency hopping spread spectrum (FH-SS) has found a number of applications in cellular systems, wireless local loop, and wireless local area networks. The suitability of slow frequency hopping code division multiple access (SFH-CDMA) is characterised, for application in third generation wireless communications. An FH architecture displays inherent frequency diversity, and consequently is resilient to the effects of intersymbol interference arising from significant time dispersion in the channel. Furthermore, interference diversity of FH-CDMA results in a robust air interface technique. It is demonstrated that FH-CDMA can support the medium rate service bearers required for UMTS and PCS, whilst providing high cellular capacity in the urban environment.
