Abstract

Performance analysis of minimum mean-squared error (MMSE) multiuser detection over a synchronous multipath channel is considered in this paper. Assuming the channel parameters are known, analysis shows that both the signal-to-noise ratio at the output of the MMSE detector and near-far resistance are related to the cross-correlation matrix of the 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
