Abstract

We propose a blind adaptive CMA post-processing technique for CDMA receiver, which is able to suppress the residual ISI and MAI symbol-by-symbol. It can be easily applied to any conventional detector at the expense of a small amount of additional computations without changing the existing algorithm. The convergence problem of CDMA that a typical cost function contains multiple stationary points is considered, and a solution for the problem is proposed. Through computer simulations, it was shown that the proposed method has stable convergence property and good performance in BER.
