✦ Synopsis
An interference suppression scheme using a block iterative, row-action projection (RAP) algorithm for direct-sequence spread-spectrum (DS/SS) code-division multiple-access (CDMA) systems is presented. The performance results for the near-far multiple-access interference scenario using the RAP algorithm are compared with a normalized least mean square (NLMS) algorithm. It is shown that the CDMA receiver employing the RAP algorithm has a faster convergence rate and a lower steady-state bit error rate compared to the receiver employing the NLMS algorithm.
