Abstract

Media-based modulation (MBM) with radio frequency (RF) mirrors is a recently proposed concept in wireless communication, which uses RF mirrors located around transmit antennas to create distinct channel paths to the receiver, primarily allowing an improvement in spectral efficiency. Existing literature has proposed spatial media-based modulation (SMBM); however, results were not presented or benchmarked. Hence, this paper, firstly presents Monte Carlo simulation results for SMBM. In addition, an easy to evaluate theoretical average bit error probability bound for SMBM is formulated and agrees well with simulation results. Finally, low-complexity mirror activation pattern selection for SMBM is investigated. Two low-complexity suboptimal selection schemes are proposed and improve the error performance of SMBM significantly.
