| Abstract: | This paper proposes an Space-Time Multiuser Detector for frequency-selective rayleigh fading synchronous CDMA channels. The detector combines the multiuser detector with array-processing, and alleviates the effects of multiple-access interference. multipath propagation and fading. Theoretical analysis and simulation show that the detector has good multiuser detecting performance. |
