Abstract

Blind adaptive multiuser detection in a MIMO system with time-varying channel gain is considered. Alamouti encoding is used for data transmission with space-time diversity and a suboptimal multiple model based adaptive algorithm is used for simultaneously tracking the channel gain and detecting the data symbols. The results obtained show the robustness of our approach in real-time detection for Rayleigh fading channels varying with time.
