Abstract
A Multicode (MC) Code Division Multiple Access (CDMA) receiver receives J encoded multicode channels (where J>1) over L multiple air signal paths (where L>1) and forms a decorrelator output vector in which for each of the J multicode channels, the interference caused by the other J-1 multicode channels has been cancelled. When the MC CDMA receiver is a coherent receiver, a pilot interference canceller cancels a received pilot signal from the J channel code of each of the received J multicode channels prior to forming the decorrelator output vector.
