  Abstract

Recently, a so called orthogonal spatial multiplexing (OSM) scheme was presented which allows simple maximum likelihood decoding at the receiver with single phase feedback. In this paper, by serially concatenating this scheme by a linear precoder, a new closed-loop SM scheme is proposed for two transmit and two receive antennas. By computer simulation results, we show that the proposed scheme outperforms the conventional SM and OSM. For the proposed code, we also propose a new simple decoding algorithm which leads to a greatly reduced decoding complexity compared with the ML receiver without any loss of error performance.
