Low-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 کاملQuadrature Amplitude Modulation
The simplest type of digital modulation involves transmitting a sequence of waveforms (“symbols”) si(t) of equal durationT where eachwaveform is chosen independently from a set of M. This allows us to transmit up to b = log2(M) bits per symbol. A common sets of such symbols are those where the real and imaginary parts of the complex baseband signal are each modulated in amplitude. This known as...
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...
متن کاملTwo High-performance Schemes of Transmit Antenna Selection for Secure Spatial Modulation
In this paper, a secure spatial modulation (SM) system with artificial noise (AN)-aided is investigated. To achieve higher secrecy rate (SR) in such a system, two high-performance schemes of transmit antenna selection (TAS), leakage-based and maximum secrecy rate (Max-SR), are proposed and a generalized Euclidean distance-optimized antenna selection (EDAS) method is designed. From simulation re...
متن کاملTransmit Antenna Subset Selection for Single and Multiuser Spatial Modulation Systems Operating in Frequency Selective Channels
Transmit antenna (TA) subset selection (TAS) is a well known multiple-input multiple-output technique that exploits the channel state information (CSI) at the transmitter in order to improve the attainable bit error rate (BER) performance. The extensive study of TAS in the context of spatial modulation (SM) has recently revealed that a significant performance gains are attainable compared to SM...
