Extended spatial modulation (ESM) is proposed as a novel spatial modulation scheme in this paper. Extended spatial modulation is a spatial modulation design where the number of active antennas can be various. The data rate could be improved as more symbols are available for transmitting and thus more information bits can be modulated during each time slot.(More)
—Flat-fading channel models are usually invoked for analyzing the performance of massive spatial modulation multiple-input multiple-output (SM-MIMO) systems. However, in the context of broadband SM transmission, the severe inter-symbol-interference (ISI) caused by the frequency-selective fading channels can not be ignored, which leads to very detrimental(More)
In conventional generalised spatial modulation (GSM) systems, the antenna combination selection is based on the distribution of channels, without channel state information (CSI). In this paper, an A-Star based heuristic method and a sequential forward selection method for antenna combination selection in GSM systems are proposed to provide a superior symbol(More)
