Adaptive Bit-Interleaved Coded Modulation MIMO System with Near Full Multiplexing Gain

An adaptive coded multiple-input multiple-output (MIMO) system with outdated channel state information (CSI) at the transmitter is proposed and investigated. By incorporating the rate-compatible punctured codes (RCPCs) and bit-interleaved coded modulation (BICM) into the adaptive MIMO system, the proposed adaptive RCPC-BICM MIMO system is shown to achieve both a near-full multiplexing gain and a robust BER against the CSI feedback delay. A comparison among various adaptive MIMO systems shows that the proposed system provides a good trade-off between the spectral efficiency, BER and system complexity.
