Quadrature Spatial Modulation Decoding Complexity: Study and Reduction

This letter presents the computational complexity reduction of the maximum likelihood-quadrature spatial modulation (QSM-ML) decoder as compared with the conventional SM-ML. Furthermore, a novel reduced-complexity (RC) sphere decoder algorithm, especially designed for QSM decoders, is proposed. It i...
