In this correspondence, we present a comprehensive performance analysis of orthogonal space-time block codes (STBCs) with receive antenna selection. For a given number of receive antennas , we assume that the receiver uses the best of the available antennas, where, typically, . The selected antennas are those that maximize the instantaneous received signal-to-noise ratio (SNR). We derive explicit upper bounds on the bit-error rate (BER) performance of the above system for any and , and for any

We show that the diversity order, with antenna selection, is maintained as that of the full complexity system, whereas the deterioration in SNR is upper-bounded by 10 log ( ) decibels. Furthermore, we derive a tighter upper bound for the BER performance for any and when = 1, and derive an expression for the exact BER performance for the Alamouti scheme when = 1. We also present simulation results that validate our analysis. Index Terms-Antenna selection, multiple-input multiple-output (MIMO) systems, performance bounds, space-time block codes (STBCs).
