Abstract

In TD-CDMA system, multi-user interference degrades the system performance. In this paper, we propose a effective multi-user detection algorithm applicable to TDD mode. We certify a channel estimation capacity by using midamble and performance of the proposed multistage interference canceller in the system complex aspect. In computer simulations, it is verified that proposed algorithm has lower complexity and better performance than conventional multi-user interference cancellation in Rayleigh fading channel.
