Abstract:This paper focuses on the initial code phase estimation, also called as acquisition, in the asynchronous multiuser CDMA system. The performance of the subspace-based MUSIC (Multiple Signal Classification) estimator is compared to the conventional matched filter. Simulation results for the communication system with ten users each having a 2-path Rayleigh fading channel and raised-cosine shaped chip waveform are presented. It is shown that the celebrated near-far resistance and the overall performance of MUSIC i… Show more
