Abstract :
In this paper, we present a stochastic analysis of the constant modulus (CM) array for time-varying channels. An expression for the mean-square error is derived, which is based on a recursion for the weight-error correlation matrix. The analysis yields an accurate model of the tracking behavior of the CM array provided the array maintains capture on the same source. Computer simulations are presented to illustrate the tracking behavior of the CM array and to verify the theoretical model
