An Analytical Approach to V-BLAST Detection with Optimal Ordering for Two Input Multiple Output Systems

In this paper, an analytical approach to performance analysis of vertical Bell laboratories layered space time (V-BLAST) detection with optimal ordering for systems with two transmit antennas is presented. The post-detection signal-to-noise-ratio (SNR) at each stage is derived and the symbol error probabilities (SEP) of the signals are then given in closed-form. The analysis takes into account the effects of optimal ordering, imperfect channel estimation and error propagation, which were rarely considered in the literature due to the difficulties in evaluation. The accuracy of the analysis is demonstrated by Monte-Carlo simulations. Key words: Symbol Error Probability, V-BLAST, Optimal Ordering, Imperfect Channel Estimation, Error Propagation
