In this paper, a reduced complexity soft-input softoutput MIMO detector is presented. The detector is intended to be used in conjunction with an error correction code. The detector combines a Sphere Decoder with a Hopfield network to calculate a max-log-map approximation. It is then combined with the error correction code in an iterative structure (turbo). The code used is a quasi-cyclic non-binary LDPC code. The simulation results demonstrate that with less computational complexity, thedoi:10.1109/wcnc.2010.5506464 dblp:conf/wcnc/LouwBM10 fatcat:z4sj67argvd3tpj6zjryikkhay
