We have proposed a multi-carrier CDMA system that eliminates the effect of multipath fading in frequency selective fading channels by employing a number of carriers modulated with a reduced chip rate PN code.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 specific bit of the desired user gets interference from two bits of any other user.The interference cancellation technique consists of two stages.The first stage removes only the interference contributed by the first interfering bit.The second stage removes all interference.The technique is showing a good performance when the channel parameters can be estimated with low error. |
