摘要：
This paper presents a hardware implementation of CMA (Constant Modulus algorithm) adaptive array algorithms as a technique for compensating multi-path fading in mobile communication. CMA is the adaptive algorithm which can suppress undesired waves without any preliminary knowledge if the desired signal is a constant, envelope signal. The Marquardt (LS-CMA), a nonlinear least-square method using CMA, is employed for optimizing weights of the array elements. The target of this paper is to implement high-speed mobile communication systems which achieve 2Mbps. The prototype experimental model demonstrates that any reference signal is not needed in the adaptive algorithm.
