%X In this paper, a low-complexity DOA estimation algorithm is presented for asynchronous DS-CDMA systems with multipath propagation. First, the influence of multiacess interferences and noise is eliminated. Then, a group of correlation matrices constituted by the interested DOA's is derived. Finally, according to the conventional MUSIC algorithm, DOA's are resolved preciously from the above matrices. The algorithm has the advantages of low computation burden and high resolution. Simulation results confirm the effectiveness of the algorithm.
