• Media-based modulation (MBM) is an attractive transmission technique that has been recently receiving increased research attention in the wireless communication domain. MBM employs the use of radio frequency mirrors to vastly improve the error performance and/or spectral efficiency of transmission schemes as compared to traditional source-based modulation techniques. Double spatial modulation (DSM) is a new multiple-input multiple-output transmission technique that aims to improve the spectral efficiency of conventional spatial modulation by increasing the number of active transmit antennas. In this study, DSM is extended to employ MBM, such as to improve error performance, and the scheme is termed double spatial media-based modulation (DSMBM). The theoretical average bit error probability of DSMBM is formulated and validated by Monte-Carlo simulation results. Lastly, coded channels are investigated. Typically, soft-output detection coupled with soft-input channel decoding yields a significant signal-to-noise ratio gain. Hence, the authors further propose soft-output maximum-likelihood detectors for the DSM and DSMBM systems.
