Diversity gain analysis of best terminal selection for single-input multiple-output WPAN systems

초록

The average symbol error rate (ASER) for the single-input multiple-output (SIMO) cyclically prefixed single-carrier (CP-SC) system with best terminal selection (BTS) is considered. Using derived closed-form expressions for the ASER and an upper bound on it, an asymptotic diversity gain is derived. Based on this result, it is shown that a QR decomposition (QRD)-based receiver and BTS are both needed to maintain the asymptotic diversity gain. Monte Carlo simulations verify the derived diversity gain analysis. © 2011 IEEE.
