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 effects on the achievable system performance,...
In generalised spatial modulation (GenSM) systems, the total number of active antenna groups is always not a power of two, which leaves room for designing an active antenna group (AAG) selection algorithm to achieve the constellation shaping gain and to improve the symbol error rate (SER). In this paper, based on uniform-cost search, a novel iterative AAG selection algorithm for GenSM systems is proposed...
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 error rate (SER) performance with CSI. The...
In this paper, an iterative zero forcing (IZF) detection scheme for generalised spatial modulation (GSM) is proposed to provide superior performance of bit error rate (BER) compared with other linear detection scheme, such as zero forcing (ZF) detection and minimum mean square error (MMSE) detection. Comparing to the optimal maximum likelihood (ML) detection, the proposed IZF detection also reduces...
In this paper, an energy-efficient spatial modulation (SM), which is called joint space and time dispersion modulation (STdM), is proposed for the multiple-input multiple-output (MIMO) frequency-selective fading channel. The proposed scheme extends the recent concept of SM to both space and time dispersion dimensions. Specifically, in the STdM scheme, only 1 out of $N_{t}$ transmit antennas (TAs)...
