In this paper, we study the design of frequency domain turbo equalization (FDTE) in single carrier (SC) multiple-input multiple-output (MIMO) systems, and prove the equivalence of two typical FDTE schemes under constant-modulus modulation. In the design of FDTE schemes, received signals and soft decision symbols obtained at the previous iteration are utilized to recover the transmitted symbols under...
Generalised spatial modulation (GSM) is extended from the concept of spatial modulation (SM). Due to its superior energy efficiency to classical multiple-input multiple-output (MIMO) techniques, GSM has attracted plenty of interest under the study of large-scale MIMO systems. In this paper, we propose a low-complexity symbol detector for GSM based on the framework of sparse Bayesian learning (SBL),...
In this letter, a novel signal vector based detection (SVD) scheme for spatial modulation (SM) system is proposed. For analytical tractability, we focus on the system in which only one antenna is active during one time slot. Through the theoretical analysis and simulation results, it is shown that the performance of SVD scheme can agree well with the result of the optimal maximum likelihood (ML) detection...
