In a multi-user direct sequence code division multiple access (DS-CDMA) system. retrieval of transmitted signals with a conventional receiver is difficult when there is chip asynchronism. multipath propagation and the associated near-far problem. Results presented shock that despite these problems an adaptive linear receiver based on a mixed cross correlation and constantmodulusalgorithm (CC-CMA) has the potential to retrieve all users simultaneously, Compared with the conventional CC-CMA algorithm. the proposed algorithm achieves faster convergence. Simulations support the improved convergence properties of the algorithm.
