Precoded Generalized Spatial Modulation for Downlink MIMO Transmissions in Beyond 5G Networks

Applied Sciences, 2020
The design of multiple input multiple output (MIMO) schemes capable of achieving both high spectral and energy efficiency constitutes a challenge for next-generation wireless networks. MIMO schemes based on generalized spatial modulations (GSM) have been

Social Mistreatment Effect on Alcohol Misuse Trajectories Is Moderated by Subcortical Network Activation During Error Processing

Addiction Biology, Volume 31, Issue 9, September 2026.
This longitudinal study found that college students displayed increased alcohol misuse over 3 years, and perceived general social mistreatment (GSM) amplified this trajectory. Functional MRI during a Stop‐Signal Task revealed that individuals who demonstrated faster motor inhibition exhibited a shallower alcohol misuse slope and diminished influence of

Precoding Aided Generalized Spatial Modulation With an Iterative Greedy Algorithm

IEEE Access, 2018
This paper divides antennas at the transmitter into several transmit antenna groups (TAGs) and extends the generalized spatial modulation (GSM) idea to a new precoding-aided multiple-input multiple-output system, which is referred to as precoding-aided ...

On the Capacity and Performance of Generalized Spatial Modulation

, 2015
Generalized spatial modulation (GSM) uses N antenna elements but fewer radio frequency (RF) chains (R) at the transmitter. In GSM, apart from conveying information bits through R modulation symbols, information bits are also conveyed through the indices ...

MMS Observations of Multi‐Species Wave‐Particle Interactions and Rapid Foreshock Evolution

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The ion foreshock is the region upstream of Earth's bow shock where magnetic field lines connect to the quasi‐parallel shock surface. Within this region, there exist a variety of backstreaming ion populations from the shock ramp that can generate ultra‐low frequency (ULF) waves through wave‐particle interactions. In this work, we use data from

Impacts of Ionospheric Conductance During the December 2021 Solar Eclipse on the Coupled Magnetosphere‐Ionosphere‐Thermosphere System

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses provide unique opportunities to investigate geospace dynamics driven by rapid, localized reductions in solar radiation. On December 4th $4\text{t}\text{h}$, 2021, a total solar eclipse occurred over West Antarctica during substorms.
