Spatial Modulation for Generalized MIMO: Challenges, Opportunities, and Implementation

TL;DR: In this paper, the authors present a comprehensive state-of-the-art survey on SM-MIMO research, to provide a critical appraisal of its potential advantages, and to promote the discussion of its beneficial application areas and their research challenges.
Journal ArticleDOI

Space shift keying modulation for MIMO channels

TL;DR: Space shift keying concepts are extended to incorporate channel coding, where in particular, they are considered a bit interleaved coded modulation (BICM) system using iterative decoding for both convolutional and turbo codes.
Journal ArticleDOI

Spatial modulation: optimal detection and performance analysis

TL;DR: The optimal detector for the so-called spatial modulation (SM) system introduced by Mesleh et al. in 2006 is derived, and it is shown that SM with the optimal detector achieves performance gains over popular multiple antenna systems, making it an excellent candidate for future wireless communication standards.

Spatial Modulation for Generalized MIMO: Challenges, Opportunities, and Implementation This tutorial paper offers a comprehensive overview of the state of the art in spatial modulation for generalized multiple-input-multiple-output (MIMO) technologies.
