摘要：

During last few years, there has been a dramatical rise in commercial, interest in code division multiple access (CDMA) systems. A CDMA system provides protection against interference, multipath, fading and jamming. Because of this, it yields capacity improvements over other access schemes. There are several interference cancellation schemes for WCDMA, which require information about all interfering active users or some channel parameters. In this paper, we present a decision feedback equalizer (DFE) for a WCDMA system in an indoor wireless Rayleigh fading environment. This system only uses information about the desired user's spreading code and a training sequence. Bit error probability (BEP) analysis of the system shows significant capacity improvements. Simulation results are included.
