A New Detection Scheme for Layer Space-time Signals

摘要：

Owing to the error propagation,the performance ofVBLAST is constrained by the accuracy of the symbolsrecovered in the previous layer when the traditional detectionsuccessive interference cancellation (SIC) algorithm is applied.The performance of VBLAST depends on the performance ofthe first detected layer.So we proposed a new detection schemethat the fast stage is detected with iterative method and thesecond stage using linear ZF detection detects others layersignals..The proposed algorithm reduces the error propagation.Simulation result states that proposed scheme outperform toZF-VBLAST about 4.5rib at 10-3 error bit rate.
