Abstract :
In this paper, we present a new iterative receiver algorithm based on sort QR decomposition to mitigating the error propagation of VBLAST. The performance of first detected layer is enhanced for it is detected iteratively, so the performance of the overall system is improved. The proposed algorithm achieves good performance compared to standard ZF-VBLAST with reduced computational complexity.
