| Abstract(in English) | In this paper, a novel multiuser detection scheme for DS/CDMA systems is proposed, which is equipped with an adaptive detector with emulating functions of communication environments at the receiving end. It is shown that under this scheme the decorrelating solution can be obtained by successively renewing despreading code sequences, with no data aids i.e., it can be estimated with the prior knowledge of signature waveforms and timings of all users. It is seen that the proposed adaptive decorrelating detector offers the same performance of Bit-Error-Rate compared with the conventional decorrelating detector and better performance of convergence characteristics compared with data aided normalized LMS algorithm. The computational complexity of the proposed algorithm is equivalent to the conventional normalized LMS algorithm. |
