Abstract :
Receive antenna selection diverrsity in MIMO-OFDM transmission is attractive because it can achieve better BER performance due to higher diversity gain obtained, keeping the cost and energy consumption low. However, how to select a suitable set of receive antenna elements is a key issue, with low computational and hardware complexity. In this paper, we propose an receive antenna directivity diversity method for a MIMO-OFDM system with RF-MEMS switches. We discuss the BER performance of the proposed method as well as conventional methods by computer simulations with the measured channel data in a 5 GHz frequency band.
