New Spatial-Multiplexing Scheme for Erasure Fading Channels

This paper proposes a new spatial-multiplexing(SM) scheme which is constructed by serially concatenating an orthogonal precoder with a conventional SM. Compared to the conventional SM, the proposed scheme achieves improved performance under erasure fading channels without any performance loss under non-erasure fading channels. Particularly the performance gain is more larger as a correlation value between two receive antennas increases.
