N2 - One of the promising techniques to achieve good bit error rate (BER) performance in a fading environment is the spatial diversity. In general, user equipment (UE) is equipped with only a few antennas due to its spatial limitation, while a large number of antennas can be equipped at the base station (BS). In this paper, we introduce a selective multi-input multi-output (MIMO) spatial diversity with subcarrier-wise UE antenna identification and selection. Maximal-ratio transmit frequency-domain equalization (MRT-FDE) and minimum mean square error combining FDE (MMSEC-FDE) are used for the orthogonal frequency-division multiplexing (OFDM) downlink and the single-carrier (SC) uplink, respectively. Computer simulation confirms that, without introducing space-time block coded transmit diversity (STBC-TD), additional diversity gain can be obtained by selective MIMO diversity.
