Abstract :
An adaptive algorithm based on linear prediction is presented for joint blind equalization and multiuser detection for asynchronous CDMA systems in multipath propagation. The linear prediction is computationally efficient and numerically robust. It is shown that the new method is insensitive to estimation error of propagation delay, or chip timing. Simulation results show that the proposed method is also near-far resistant, and compare favorably to many existing methods.
