Item Low-Complexity Generalized Spatial Modulation Schemes Using Codebook-Assisted MIMO Detectors(Institute of Electrical and Electronics Engineers Inc.) Chen, Y.; Cheng, W.; Li, C.; Haas, Zygmunt J.; 68658964 (Haas, ZJ); Haas, Zygmunt J.Generalized spatial modulation (GSM) is an attractive transmission technique for multiple-input multiple-output (MIMO) systems because of its spectral efficiency and energy efficiency. The maximum likelihood (ML) detector provides the optimal performance for GSM signal detection, but also leads to a high level of detection complexity. In this paper, both hard-decision and soft-decision detectors, which are based on a low-complexity codebook-assisted tree-search algorithm, are investigated. In addition, outer low-density parity-check (LDPC) codes are designed such that the concatenated schemes are able to provide error performances which are very close to those of the schemes using conventional detectors, but with a much lower level of computational complexity.
