Abstract:

Space-time transmission techniques, which make full use of the rich scattering channel with multiple transmit and receive antennas, can greatly increase the spectral efficiency. The conventional V-BLAST (Bell laboratories layered space-time) detection algorithm estimate symbols with the expected SNRs ordering. In this paper, a novel BLAST detection algorithm based instantaneous error ordering (IEO-BLAST) is proposed. The proposed BLAST detection algorithm obtains the additional diversity with instantaneous error ordering and reduces the effect of the error propagation. Therefore, the performance of the BLAST architecture is greatly improved. In addition, the simplified version of IEO-BLAST detection algorithm (SIEO-BLAST) is derived. And the performance of simplified algorithm has little degradation. The selection capacity (SC) is defined to represent the performance of the algorithm with successive interference cancellation.
