Antenna selection for MIMO-OFDM systems

In this paper, a new subcarrier-by-subcarrier antenna selection scheme for a multiple input multiple output (MIMO) space–frequency block coded (SFBC) orthogonal frequency division multiplexing (OFDM) system concatenated with a turbo product code is presented. We examine the coding and diversity advantage of the SFBC-OFDM system with antenna selection using average SNR gain, outage probability and BER analysis validated by numerical simulation. The system performance of different forms of the proposed scheme is evaluated and compared. It is shown that the proposed scheme can greatly improve the performance of the conventional SFBC-OFDM systems.
