Abstract

A new iterative Zero-Forcing BLAST with QR Decomposition algorithm improving the performance over error propagation is proposed in this paper. In the algorithm, much effort is made on several iterations to obtain the high performance substreams. Simulation results show that the new algorithm greatly improve the performance of the traditional QR detection algorithm with reasonable increase of computation complexity. This new iterative detection algorithm also has better performance and lower complexity than another iterative QR Detection approach in [3].

Keywords: MIMO iteration detection V-BLAST，QR detection
