Abstract
In this work, we propose a blind channel equalizer for a DS-CDMA forward link over unknown frequency-selective fading channels. The proposed downlink receiver exploits the fact that all synchronized orthogonal CDMA signals go through the same channel to recover the desired signal with a channel equalizer followed by a despreader. Such a scheme allows the receiver to operate blindly in a time-varying environment for both periodic CDMA and aperiodic CDMA systems
