Blind Channel Equalization in Downlink MC-CDMA Systems Exploiting Guard Interval Redundancy and Excess Codes

Abstract

This paper introduces a new blind time domain equalization (TEQ) technique for downlink MC-CDMA systems operating in multipath fading channels. This equalization exploits the guard interval redundancy (GI) together with the excess codes (EC). Indeed, since in CDMA-based wireless systems, the number of users per cell is significantly less than the spreading… (More)
