The performance of a linear multiuser detector for Direct-Sequence (DS)-Code-Division Multiple-Access (CDMA) is studied assuming a random signature sequence model and Minimum Mean Squared Error (MMSE) detection. Performance criteria considered are Near-Far Resistance (NFR) and Signal-to-Interference Ratio (SIR). An analytical approximation for the probability density function (pdf) of the NFR is presented, which is accurate when the ratio of users to processing gain is small. The pdf for the SIR is obtained via computer simulation, and our results show that the spread in SIR over the user population can be significant.
