A differential scheme for Spatial Modulation

2013 IEEE Global Communications Conference (GLOBECOM), 2013
In this paper, by considering the case of two transmit antennas, we propose a novel approach for introducing differential signaling into Spatial Modulation (SM)/Space-Shift Keying (SSK) and thus develop a differential SM/SSK (DSM/DSSK) scheme, where neither the transmitter nor the receiver has access to channel state information.

Pre-Coding Aided Differential Spatial Modulation

2015 IEEE Global Communications Conference (GLOBECOM), 2014
In this paper, we propose a novel Multiple Input Multiple Output (MIMO) scheme based on Spatial Modulation (SM) and termed as Pre-coding aided Differential Spatial Modulation (PDSM). By mapping information to the receiver side space-time transmit blocks and conducting differential modulation, the PDSM scheme achieves further reduced receiver side ...

Space-Time Block Coded Differential Spatial Modulation

IEEE Transactions on Vehicular Technology, 2017
In this paper, a novel multiple-input multiple-output (MIMO) transmission scheme termed space-time block coded differential spatial modulation (STBC-DSM) is proposed. It employs the hybrid concept of differential spatial modulation (DSM) and space-time block coding (STBC) to exploit the diversity benefits of STBC without the channel state information ...

Optical Preprocessing and the Differentiating Spatial Light Modulator

Topical Meeting on Machine Vision, 1987
Photoaddressed spatial light modulators (SLMs) or light valves generally employ a longitudinal electro-optical effect, where the electro-optic voltage is controlled by a photoactive element (e.g., phototitus, Hughes liquid-crystal light valve).1 These devices provide image amplification and incoherent-to-coherent light conversion.

A differential reflectometer for spatial modulation spectroscopy

Journal of Physics E: Scientific Instruments, 1976
A simple double beam reflectometer is described in which the reference and the perturbed beams have optical paths exactly equivalent in principle. Results of experiments illustrating its range of use and its performance are given.

Liquid-Crystal Differentiating Spatial Light Modulator

SPIE Proceedings, 1986
A nematic liquid-crystal spatial light modulator based on a transverse electro-optic effect is demonstrated. The transverse field is derived from the write light intensity gradient; therefore the device operates in a differentiating or edge enhancing mode.

An Optimal Low-Complexity Detection Algorithm for Differential Spatial Modulation

2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019
Differential spatial modulation (DSM) is developed by spatial modulation (SM), which does not require the channel state information (CSI) at receiver. The optimally classic detection algorithm is maximum-likelihood (ML), but it has very high computational complexity.

Differential Spatial Frequency Modulation with Orthogonal Frequency Division Multiplexing

2018 IEEE Global Communications Conference (GLOBECOM), 2018
Spatial modulation orthogonal frequency division multiplexing with subcarrier index modulation (ISM-OFDM) is a novel OFDM technique that conveys additional information bits by active antenna indices and grouped subcarrier indices. However, it takes a huge amount of resources to acquire the channel state information (CSI) at the receiver. In this paper,

Space-Time Block Coded Rectangular Differential Spatial Modulation

2018 IEEE International Conference on Communications (ICC), 2018
In this paper, a novel space-time block coded rectangular differential spatial modulation (STBC-RDSM) is proposed for multiple-input and multiple-out (MIMO) system, which combines the space-time block coding (STBC) and rectangular differential spatial modulation (RDSM) to take the advantages of RDSM and STBC systems, while avoiding the drawbacks of ...
