摘要

In this paper, we investigate low complexity channel state selection algorithms in single input multiple output media-based modulation (SIMO-MBM) based on maximizing the minimum Euclidean distance of constellation. We propose two channel state selection algorithms called CS-MBM and CS-MSBM for SIMO-MBM with only MBM information transmitted and with both MBM and source-based modulation (SBM) information transmitted, respectively. The proposed channel state selection algorithms can reduce the complexity significantly especially at large constellation size. Simulation results show that although both algorithms suffer from a little loss in performance with large signal-to-noise (SNR) at small constellation size, they perform well at large constellation size and even better at some specific SNR region. These two algorithms can also be combined with other reduced complexity schemes to further decrease the complexity of channel state selection.
