An equal gain combining DPSK MC-CDMA system for fast fading mobile downlink channels

This paper describes a multi-carrier code division multiple access downlink system which can be used in mobile or broadcast radio communication applications. It employs a novel form of differential phase shift keying, in which the phase shift keying is applied in the transmitter after all the users symbols have been combined. Theoretical performance predictions and results of simulations are presented and comparison is made with other equivalent MC-CDMA and DS-CDMA downlink systems.
