Abstract :
We have proposed a multi-carrier DS-SS CDMA system that eliminates the effect of multipath fading. Instead of multipath diversity, frequency diversity is obtained. This paper presents a co-channel interference cancellation technique and applies it to the multi-carrier CDMA system. Any bit of the desired user gets interference from two bits of any other user. The interference cancellation technique first removes the interference contributed by the first interfering bit then removes all interference
