Abstract

In this paper, we propose a time-varying multi-path VECTOR CHANNEL model for the cellular CDMA-based communication system environment. A modified CMA to use in CDMA system environment is presented. We assume that the angular spread of each source to be large so that fading is non-coherent across the elements of the antenna array. The proposed modified CMA algorithm is more suitable in studying the convergence performance and the radiation patterns of uniform linear for tracking signal sources in CDMA mobile systems. Comparing the signal to noise ratio at the output of the algorithm of a uniform linear with the theoretical results proves the efficiency of the proposed algorithm. The BER performance with DBPSK modulation is also compared for CMA and VS-CMA algorithms in linear array.
