Abstract:
An antenna selection technique (transmitter/receiver antenna selection) that reduces the cost of the MIMO system while maintaining high performance. A combined selection algorithm for MIMO-OFDM is provided which offers the best tradeoff between spatial correlation and instantaneous SNR. In one case, antenna selection is based on instant channel information. In another case antenna is based on statistical channel state information. In another case, antenna selection is based on a hybrid of instant channel state information and statistical channel state information.
