“…Foschini [1] showed that flat fading MIMO channels have enormous capacity, which grows linearly with the number of transmit antennas. Meanwhile, multiple antennas transmission brings co-channel interference between antennas and multipath interference between the delay replicas of signals from different transmit antennas [2][3][4] . To improve the reliability of digital communications affected by severe channel states in MIMO systems, Hybrid Automatic-RepeatreQuest (HARQ) schemes combined with Forward Error Correction (FEC) and ARQ are often employed as countermeasures.…”

A multi-Cyclic Redundancy Check (CRC) selective Hybrid Automatic-Repeat-reQuest (HARQ) scheme for improving the throughput efficiency of Multiple Input Multiple Output (MIMO) systems is proposed in this paper. According to different feedback information from the receiver, the proposed HARQ scheme employs two strategies, referred to as retransmission frame selection and space diversity. These two strategies decrease the successive frame errors upon retransmission. Theoretic analysis and computer simulation results show that this HARQ scheme achieves higher throughput than the existing HARQ schemes even in poor conditions of low Signal-to-Noise Ratio (SNR).
