摘要：

This paper presented a blind adaptive step-size constant modulus algorithm (AS-CMA) for suppression of multiple-access interference (MAI) and narrow-band interference (NBI) in direct-sequence/code-division multiple-access (DS/CDMA) systems and compared this algorithm with adaptive step-size LMS algorithm. The simulations indicate that the performance of this algorithm is better than that of AS-LMS in convergence and stability and it can adapt to the changes of the environment.
