  • A subspace-based time delay sequential estimation algorithm named MUSIC-SEA is presented for asynchronous bandlimited DS-CDMA systems in multipath fading channels. The sequential estimation idea is introduced, and the knowledge of the estimated time delays is involved in the subsequent estimation procedures. The whole procedure can be described as follows: the noise subspace is estimated first, and then coarse estimation and fine search of time delay are implemented for every time delay sequentially. The iterative steps are presented, the performance of the algorithm is analyzed, and simulations are carried out. The results show that the algorithm can mitigate the interference of multipath and provide time delay estimation with high probabilities and high accuracy.
