Efficient Transmit Antenna Selection for Correlated MIMO Channels

摘要: While multiple-input multiple-output (MIMO) system gives many advantages to wireless communication, the complexity of multiple RF chains a burden system. Antenna selection is introduced as technique reduce burden. On transmit antenna scheme, exhaustive search for optimal set quickly becomes impractical adopting more antennas. To searching, we propose an efficient method. We first make threshold by using Poincare separation theorem. Instead search, select subset that exceeds threshold. exponentially correlated channel array antennas, give order reducing further. from most remotely located which in generally less closely antennas correlated. Finally, show BER performance and tradeoff relation between Monte-Carlo simulations.
