Abstract :
In this paper, we examine the improvements in the performance of a VBLAST-based multiple-input multiple-output (MIMO) system equipped with a recently proposed smart passive receive antenna selection (SPRAS) technique and compare it with the other existing antenna selection schemes. The simulation results show the superiority of SPRAS compared to the other selection techniques. Specifically, when the smart passive receive antenna aperture size increases beyond a limit, the bit-error-rate (BER) improves significantly. Furthermore, SPRAS performs as well as a full-complexity MIMO structure but with fewer RF chains
