Abstract
The paper proposes an improved blind MOE adaptive space-time multiuser detection scheme in multipath CDMA channels, which combines a POR (power of covariance matrix R) technique with blind MOE adaptive space-time multiuser detection. Moreover, we analyze the performance of the improved blind MOE space-time multiuser detector according to the effect of white noise, data sample number and positive integer u in cost function. The theoretic analysis and simulation results show that the performance of the novel space-time multiuser detector asymptotically converge to the blind MMSE space-time multiuser detector on condition that smaller noise power, larger enough data sample number and u/spl rarr//spl infin/.
