摘要：
This paper deals with direction-of-arrival (DOA) estimation based on iterative MUSIC searching technique for the code division multiple access (CDMA) system. It has been shown that the iterative searching technique suffers from the local maximum searching problem, causing acquisition errors in DOA estimation. In conjunction with a genetic algorithm (GA) for selecting initial search angle, we present an efficient approach to achieve the advantages of iterative DOA estimation with fast convergence and more accuracy estimate over existing conventional spectral searching methods. Finally, several computer simulation examples are provided for illustration and comparison. (C) 2010 Elsevier Ltd. All rights reserved.
