“…However, the low number of RF chains limits the transmission rate of the SM scheme. In order to increase its throughput, multiple activated TA based SM variants were proposed in [12]- [19]. Specifically, in the Generalized SM (GSM) scheme [12]- [15], N u out of N t TAs are activated to transmit different symbols, so that the transmission rate is significantly increased.…”

“…In [16]- [17], the number of activated TAs ranged from one to N t . Additionally, GSM combined with Space Time Block Coding (STBC) structures was designed in [18]- [19]. However, the above SM variants have the common feature that the information bits are conveyed both by the active TA index as well as by the Amplitude Phase Modulation (APM) symbols.…”

A novel Multiple-Input and Multiple-Output (MIMO) transmission scheme termed as Generalized Quadrature Spatial Modulation (G-QSM) is proposed. It amalgamates the concept of Quadrature Spatial Modulation (QSM) and spatial multiplexing for the sake of achieving a high throughput, despite relying on low number of Radio Frequency (RF) chains. In the proposed G-QSM scheme, the conventional constellation points of the spatial multiplexing structure are replaced by the QSM symbols, hence the information bits are conveyed both by the antenna indices as well as by the classic Amplitude/Phase Modulated (APM) constellation points. The upper bounds of the Average Bit Error Probability (ABEP) of the proposed G-QSM system in high throughput massive MIMO configurations are derived. Furthermore, an Efficient Multipath Orthogonal Matching Pursuit (EM-OMP) based Compressive Sensing (CS) detector is developed for our proposed G-QSM system. Both our analytical and simulation results demonstrated that the proposed scheme is capable of providing considerable performance gains over the existing schemes in massive MIMO configurations.

“…In order to exploit the diversity gain of the QSM and SM system, the diversity oriented QSM and SM designs were investigated in [11]- [14]. Specifically, in [13], an Enhanced SM relying on an Arbitrary Transmit Antenna (ESM-ATA) configuration and single or twin RF stages was proposed. Specifically, in the ESM-ATA scheme, a novel Space Time Block Coding (STBC) based SM structure was presented, which is capable of outperforming the existing STBC-SM schemes [11] in terms of its Bit Error Ratio (BER), despite its modest complexity.…”

A novel Multiple-Input and Multiple-Output (MIMO) transmission scheme termed as Space-Time Block Coded Quadrature Spatial Modulation (STBC-QSM) is proposed. It amalgamates the concept of Quadrature Spatial Modulation (QSM) and Space-Time Block Coding (STBC) to exploit the diversity benefits of STBC relying on sparse Radio Frequency (RF) chains. In the proposed STBC-QSM scheme, the conventional constellation points of the STBC structure are replaced by the QSM symbols, hence the information bits are conveyed both by the antenna indices as well as by conventional STBC blocks. Furthermore, an efficient Bayesian Compressive Sensing (BCS) algorithm is developed for our proposed STBC-QSM system. Both our analytical and simulation results demonstrated that the proposed scheme is capable of providing considerable performance gains over the existing schemes. Moreover, the proposed BCS detector is capable of approaching the Maximum Likelihood (ML) detector's performance despite only imposing a complexity near similar to that of the Minimum Mean Square Error (MMSE) detector in the high Signal to Noise Ratio (SNR) regions.
