نویسندگان
چکیده
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 compensating the channel

Low-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 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 کاملEstimating the Number of Wideband Radio Sources
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
متن کاملLow-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 کاملDetection of Generalized Media-based Modulation Signals using Multi-layered Message Passing
In this paper, we consider generalized media-based modulation (GMBM) where transmit antennas and RF mirrors (which are parasitic elements placed near the transmit antennas as digitally controlled scatterers) are indexed simultaneously to convey information bits. GMBM systems offer the advantages of high rates, reduced transmit RF hardware complexity, and improved performance compared to convent...
