Multiuser Detection for Synchronous DS-CDMA in AWGN Channel

Abstract
In conventional correlation receiver, the capacity of a single cell using CDMA is limited by Multiple Access Interference (MAI). To overcome this drawback, several advanced receiver structures have been proposed. Unlike the conventional receiver which treats multiple access interference (MAI) as if it were AWGN, multiuser receivers treat MAI as additional information to aid in detection. In this paper I present a comparative study of the most widely discussed receiver structures: the Conventional Matched Filter receiver, the Decorrelator receiver, the Minimum Mean Square Error (MMSE) receiver, and the Successive Interference Cancellation receiver. BER performances of the above mentioned multiuser receivers are studied as a function of SNR, number of users and processing gain.
Keywords- Direct-sequence code division multiple access (DS-CDMA), Multi-user detection (MUD), Additive White Gaussian Noise (AWGN), Multiple Access Interference (MAI), Minimum Mean Square (MMSE), Signal-to-Noise Ratio(SNR).
