Abstract
A linear recursive "one-shot" decorrelator for asynchronous CDMA systems is developed. It has a lower complexity and better performance than existing "one-shot" decorrelators while eliminating all multiple access interference (MAI). This decorrelator does not exploit any signal energy information. Through simulation, this decorrelator is shown to be near-far resistant in both AWGN and fading channel.
