Generalized spatial modulation in indoor wireless visible light communication

open access: yes, 2014
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses Nt light emitting diodes (LED), but activates only Na of them at a given time. Spatial modulation

The dynamic functional connectivity peak index: Detection of interictal epileptic activity with fMRI

open access: yesEpilepsia, EarlyView.
Abstract Objective Epileptogenic zone (EZ) localization is crucial for surgical treatment of patients with medication‐resistant epilepsy. Although simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) can detect interictal discharges for EZ localization, clinical adoption is limited by the need for specialized ...

A Semi‐empirical Framework for Dst Prediction Based on Global MHD Simulation of Earth's Magnetosphere

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract This study develops a semi‐empirical framework for Dst index forecasting by integrating the PPMLR‐MHD model of Earth's magnetosphere with four established empirical models (Burton, UCB, AK2, and Wang). The framework partitions the physics: global magnetopause and tail currents are simulated by MHD, while the ring current contribution is ...

On the Capacity and Performance of Generalized Spatial Modulation

open access: yes, 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 ...
