Abstract :
In this paper, the blind variable step-size LMS algorithm is developed for asynchronous DS-CDMA systems. The performance of the resulting system is compared to that of the blind LMS algorithm using computer simulations. It is shown that the proposed blind VSLMS algorithm reduces the BER of the system which can accordingly lead to a more reliable mobile communication.
