Abstract :
The performance of the adaptive MMSE maximum likelihood CDMA receiver is analysed. Instead of the matched filter (MF) bank as the generator of sufficient statistics for maximum likelihood detection (MF-ML), a bank of minimum mean squared error (MMSE) filters is used. It is shown that the proposed MMSE-ML receiver achieves increased information capacity in a multicellular environment. Numerical results showing the performance of the MMSE-ML receiver in a multipath channel environment are presented
