Constrained optimisation based space-time-code blind receiver in CDMA systems

摘要

A space-time-code (STC) blind receiver is proposed. The receiver has the advantages of constrained minimum output energy (CMOE) blind multiuser detectors and space-time (ST) 2D-Rake receivers and overcomes their limitations. It can make full use of spatial, temporal and code signatures involved in the desired user's signal to suppress multiuser access interference and combine multipath components.
