CASTILLO-SORIA, Francisco Rubén et al. Spatial Modulation, a Comparison of Basic Transmission Techniques. Ing. invest. y tecnol. [online]. 2016, vol.17, n.2, pp.273-282.  Epub 04-Abr-2022. ISSN 2594-0732.

This paper introduces a general framework for the analysis of single user Multiple Input-Multiple Output (MIMO) transmission schemes using Spatial Modulation (SM). We present a comparative analysis for the four basic SM schemes considering: Bit Error Rate (BER) performance, detection complexity, spectral efficiency and total amount of transmit antennas used. Results show that single RF chain schemes have better performance while generalized versions have better spectral efficiency. Results also show that all SM schemes have reduced detection complexity when compared to the conventional Spatial Multiplexing/Successive Interference Cancelation (SMux/SIC) scheme, however the amount of transmit antennas used for SM schemes is significantly higher than the required by the conventional SMux scheme. Additionally, a scheme which combines SM and SMux techniques is analyzed. These results can be useful as design criteria for the next generation of wireless communication systems.
