摘要
A space-time-code (STC) blind receiver is proposed in this paper. The receiver can operate in a frequency-selective fading environment with knowledge of the desired user's spreading code but not its channel characteristics. It integrates the advantages of constrained minimum output energy (CMOE) blind multiuser detector and conventional space-time (ST) 2D-RAKE receivers and overcomes their limitations. It can make full use of spatial, temporal and code signatures involved in desired user's signal to suppress multiuser access interference (MAI) and combine multipath components. Neural network based implementation of the receiver is also studied.
