Genetic iterative search-centre-shifting K-best sphere detection for rank-deficient SDM-OFDM systems
Electronics Letters, 44, (8), .
A generic sphere-detection (SD) scheme is proposed, which substantially reduces the detection complexity by decomposing it into two stages, namely the generic iterative search-centre-update phase and the reduced-complexity search around it. This two-stage philosophy circumvents the high complexity of channel-coded soft-decision aided SDs.
