Combination of multiple-input-multiple-output and non-orthogonal multiple access (MIMO–NOMA) is a promising multiple-access technology, which can greatly improve spectral efficiency and reduce latency. Among major topics of MIMO–NOMA, an interesting one is how to construct suitable multiuser codes for MIMO–NOMA. In previous works, multiuser codes require to be redesigned when the number of users,...
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 a novel detection algorithm based on polynomial expansion of iterative zero forcing (IZF) detection algorithm for generalised spatial modulation (GSM) system is proposed. Comparing with traditional IZF detection algorithm, polynomial expansion iterative zero forcing (PE-IZF) detection algorithm has a lower computational complexity, and it has much lower complexity than optimum maximum...
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...
