Beyond Mean Solar Wind Conditions: Turbulence‐Aware Forecasting of the AE Index

Space Weather, Volume 24, Issue 7, July 2026.
Abstract The auroral electrojet (AE) index is a key indicator of high latitude geomagnetic activity and is widely used in operational space weather monitoring, yet forecasting AE from upstream solar wind conditions remains challenging due to nonlinear coupling, internal magnetospheric dynamics, and multiscale variability.

Generalized spatial modulation for large-scale MIMO systems: analysis and detection

, 2014
Generalized Spatial modulation (GSM) uses nt antenna elements but fewer radio frequency chains (nrf) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with nrf = 1 and nrf = nt, respectively.
