Impact of Ionospheric Scintillations on GNSS Availability and Precise Positioning

open access: yesSpace Weather, Volume 23, Issue 2, February 2025.
Abstract For many applications where accuracy, availability, and integrity are essential, such as geodetic positioning and civil aviation, Global Navigation Satellite Systems (GNSS) are indispensable. However, GNSS signal dependability is severely hampered by ionospheric disturbances, especially equatorial plasma bubbles (EPBs), particularly in ...

A squeeze‐and‐excitation network for SNR estimation of communication signals

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
This paper presents a novel deep learning approach that uses a power spectrum generated through overlapping segmentation as input to a neural network for SNR estimation. The performance of SNR estimation has been enhanced by integrating an augmented squeeze‐and‐excitation (SE) attention mechanism with a residual block fusion module, employing multiple ...

Layered BPSK for High Data Rates

open access: yes, 2018
This paper proposes a novel transmission strategy, referred to as layered BPSK, which allows two independent symbol streams to be layered at the transmitter on a non-orthogonal basis and isolated from each other at the receiver without inter-stream interference, aiming to achieve high data rates.
