Abstract :
It has been shown that employing a higher order constellation in conjunction with CDMA can improve the performance of a multiuser system in severe multipath channels. We verify that the performance improvement gained by the above interference suppression technique in the multiuser case continues to hold in the multiuser environment with narrowband Gaussian interference
