| Abstract: | Multiuser signal detection is a theory concerning the multiple access interferences in CDMA networks, which is given more and more attention recently. This paper focuses on the performance analysis of the Linear Unbiased Minimum Variance ( LUMV) multiuser detectors.The error probability formula of the detector, together with its upper and lower bounds, are derived.The asymptotic efficiency is also given. The effect of synchronous error is analysed with computer simulations . |
