Differential Transmission Schemes for Generalized Spatial Modulation [PDF]
Differential modulation schemes are very relevant in receivers having power and processing limitations, as these schemes dispense with the need for knowledge of channel coefficients for symbol detection. Spatial modulation (SM) is a scheme used in multi-antenna transmission scenarios where the data is transmitted in the amplitude, phase and spatial ...

Deep Learning-Aided OFDM-Based Generalized Optical Quadrature Spatial Modulation
In this paper, we propose an orthogonal frequency division multiplexing (OFDM)-based generalized optical quadrature spatial modulation (GOQSM) technique for multiple-input multiple-output optical wireless communication (MIMO-OWC) systems. Considering the

On the Capacity of Generalized Quadrature Spatial Modulation
In this letter, the average mutual information (AMI) of generalized quadrature spatial modulation (GQSM) is first derived for continuous-input continuous-output channels. Our mathematical analysis shows that the calculation error induced by Monte Carlo integration increases exponentially with the signal-to-noise ratio.

Codebook-based precoding for generalized spatial modulation with diversity
This paper investigates codebook-based precoding for spatial modulation (SM) and generalized spatial modulation (GSM) systems. Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT).

Iterative generation of holograms on spatial light modulators [PDF]
Iterative learning procedures on a hybrid electro-optic system can be employed to generate holograms on inexpensive liquid-crystal-television spatial light modulators. The algorithm takes into account random electronic noise in the system and compensates for spatial-light-modulator distortions.

A Unified Precoding Scheme for Generalized Spatial Modulation [PDF]
Generalized spatial modulation (GSM) activates $n_{t}$ out of $N_{t}~(1 \leq n_{t} available transmit antennas, and information is conveyed through $n_{t}$ modulated symbols as well as the index of the $n_{t}$ activated antennas. GSM strikes an attractive tradeoff between spectrum efficiency and energy efficiency.

Improving Generalized Spatial Modulation Using Translation Patterns [PDF]
Generalized spatial modulation (GSM) is a spectral-efficient technique used in multiple-input multiple-output (MIMO) wireless communications when the number of radio frequency chains at the transmitter is less than the number of transmit antenna elements.
