Orthogonal Least Squares Detector for Generalized Spatial Modulation
IEEE Transactions on Wireless Communications, 2021Generalized spatial modulation (GSM), which is a novel multiple-input multiple-output (MIMO) transmission technique, has attracted massive research attention in recent years. In this paper, we first utilize the orthogonal least squares (OLS) based detector for GSM detection.

Antenna Grouping Based Generalized Spatial Modulation System
2021 IEEE/CIC International Conference on Communications in China (ICCC), 2021Spatial modulation (SM) technology [1], compared with the vertical Bell Labs layered space-time (V-BLAST) [2] and multiple-input and multiple-output (MIMO) [3] schemes, can significantly combat the inter-channel interference (ICI) and reduce the detection complexity at the receiver.

Holographic contour generation by spatial frequency modulation
Applied Optics, 1982A contouring method by spatial frequency modulation using hologram interferometry is presented. The principle is that Young's fringes produced by tilting the illumination ray are modulated by the object shape and demodulated by tilting the observation ray to generate depth contours. The problems of fringe localization and visibility in the arrangements

Diffraction-based determination of the phase modulation for general spatial light modulators
Applied Optics, 2006We describe a characterization method based on diffraction for obtaining the phase response of spatial light modulators (SLMs), which in general exhibit both amplitude and phase modulation. Compared with the conventional interferometer-based approach, the method is characterized by a simple setup that enables in situ measurements, allows for ...

Antenna Grouping in Dual-Polarized Generalized Spatial Modulation
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017While multiple-input multiple-output (MIMO) is considered as the key enabling technology for high data rate wireless communications, it faces several major challenges in the 5th generation MIMO systems due to limited number of radio frequency (RF) chains and space restrictions. In light of this, generalized-spatial modulation (GSM) and dual- polarized (

Spatial Modulation for Improved Performance of Next-Generation WLAN
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017Next-generation wireless networks target dense deployment scenarios where many heterogeneous devices, from high-end laptops to low-power Internet of Things (IoT) devices and wearables, must coexist and operate reliably. With increased deployment of IoT devices and wearables, increasing the energy efficiency without increasing complexity#x002F;cost is ...

Low-Complexity Detection for Generalized Multistream Spatial Modulation
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019This work proposes a suboptimal detection algorithm for generalized multistream spatial modulation. Many suboptimal detection algorithms for spatial modulation use two-stage detection schemes where the set of active antennas is detected in the first stage and the transmitted symbols in the second stage.

Enhanced-Reliability Cyclic Generalized Spatial-and-Temporal Modulation
IEEE Communications Letters, 2016In this letter, we propose temporal modulation as a new dimension to enhance the performance of spatially modulated space-time block codes (STBCs). We efficiently integrate a cyclic spatially modulated codebook with temporal permutations over four consecutive time slots.

Generalized 3-D Constellation Design for Spatial Modulation
IEEE Transactions on Communications, 2017Spatial modulation (SM) conveys information bits by utilizing both the antenna index and complex symbols to form a 3-D constellation. Similar to 2-D modulation, the structure of 3-D constellation could greatly affect the transmission reliability. In this paper, a generalized 3-D constellation design is proposed to optimize the constellation diagram ...

Signal points allocation for generalized enhanced spatial modulation
Transactions on Emerging Telecommunications TechnologiesAbstractIn this paper, making full use of the spatial domain of transmit antennas (TAs) and keeping the characteristic of the squared minimum Euclidean distance (MED) between the transmitted spatial vectors (TSVs), generalized enhanced spatial modulation with signal points allocation (GESM‐SPA) is proposed to expand the size of signal spaces for ...
