Abstract

A method for intercarrier interference (ICI) mitigation in MC-DS-CDMA systems based on the autocorrelation properties of the CDMA codes is presented. The proposed transmission scheme does not imply additional complexity to the system and the bit error rate at the receiver reaches the bound of performance of a MC-DS-CDMA system without ICI.
