摘要：
Performance analysis of the minimum mean-square error (MMSE) multiuser detection over synchronous multipath channel is considered in this paper. Assuming the channel parameters are known, analysis show that both the signal-to-noise ratio (SIR) at the output of MMSE detector and near-far resistance are related to the crosscorrelation matrix of combined spreading waveforms. Computation results demonstrate that the MMSE detector can achieve good performance under severe conditions, including large number of users and large channel length.
