Abstract:In multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems, several detection schemes have been developed for high error performance and low complexity. In several detection schemes, maximum likelihood (ML) and QRD-M have optimal error performance. However, these detection schemes have very high complexity. Thus, this paper proposes reduced complexity of QRD-M detection scheme in MIMO-OFDM systems. The proposed detection scheme has two stages, i.e. partial zero-forcing (ZF… Show more
