Low-complexity detection of quadrature spatial modulation
ELECT Quadrature spatial modulation (QSM) is a recently proposed multipleinput multiple-output transmission scheme which improves the spectral efficiency of classical spatial modulation (SM) by increasing the number of information bits transmitted by antenna indices. In QSM, a complex data symbol is decomposed into its real and imaginary components; then, these two components are independently ...
متن کاملLow-Complexity Signal Vector Based Detection Algorithm for Spatial Modulation
In this paper, signal vector based detection (SVD) algorithm for spatial modulation (SM) is modified to achieve a near maximum-likelihood (ML) performance and reduces the complexity compared to ML. First, the proposed low-complexity SVD (LC-SVD) algorithm orders the antenna index list based on the angle between the received vector y and the channel vector j h , and then it estimates symbol by c...
متن کاملLow-complexity Detection and Transmit Antenna Selection for Spatial Modulation
In this paper, we propose a novel low-complexity detection technique for conventional Spatial Modulation (SM). The proposed scheme is compared to SM with optimal detection (SMOD), SM with signal vector based detection (SM-SVD) and another reduced complexity detection technique, presented in the literature. The numerical results show that the proposed scheme can match the error performance of SM...
متن کاملLow-Complexity Detection Scheme for Generalized Spatial Modulation
Abstract—Generalized spatial modulation was recently proposed, in which only part of the transmit antennas are activated to send the same complex symbol. Compared to Spatial Modulation (SM), it can offer spatial diversity. Moreover, it is no longer limited to the number of the transmit antennas. In this letter, a low complexity detection scheme is presented, which can achieve a near Maximum-Li...
متن کاملComplex Quadrature Spatial Modulation
scheme referred to as complex quadrature spatial modulation (CQSM). In contrast to quadrature spatial modulation (QSM), CQSM transmits two complex signal constellation symbols on the real and quadrature spatial dimensions at each channel use, increasing the spectral efficiency. To this end, signal symbols transmitted at any given time instant are drawn from two different modulation sets. The fi...
