Abstract
Linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. A modified version of the receiver, called the LMMSE-RAKE receiver, has previously shown promising performance in frequency-selective fading channels. In this paper, both the convergence and BER performance of an adaptive LMMSE-RAKE receiver is compared to several other known blind adaptive single-user receivers. The results show that the proposed blind adaptive receiver can be used to improve the convergence and BER performance in comparison to other known blind adaptive receivers.
