Age‐of‐Information‐Aware Bandwidth Resource Allocation Strategy for NR‐V2X

IET Communications, Volume 20, Issue 1, January/December 2026.
3rd Generation Partnership Project (3GPP) introduces new medium access control features in New Radio Vehicle‐to‐Everything (NR‐V2X) Mode 2, such as the semi‐persistent scheduling re‐evaluation mechanism, and specifies decentralised congestion control based on system‐level metrics including channel busy ratio and channel occupancy ratio, these ...

Deep‐Learned Channel Estimation for MIMO‐OFDM System by Exploiting Frequency‐Space Correlation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
In massive MIMO–OFDM systems, accurate channel state information acquisition is vital for reliable transmission. Traditional methods fail to fully exploit sparse channel correlation, so an attentive residual autoencoder network is proposed. It uses an autoencoder with attention and residual connections to capture frequency–space correlation, and ...

Exact Analysis of SIR Performance for the Mobile OFDM Communication Systems Over the Underwater Acoustic Channel

Electronics Letters, Volume 62, Issue 1, January/December 2026.
1.This paper develops an analytical model to calculate the signal‐to‐interference ratio performance of mobile orthogonal frequency division multiplexing underwater acoustic (UWA) communication systems. 2.The model accounts for UWA channel distortion and non‐uniform Doppler effects, maintaining high accuracy across a range of Doppler shift magnitudes. 3.

A new reduced-complexity detection scheme for zero-padded OFDM transmissions

EURASIP Journal on Wireless Communications and Networking, 2011
Recently, zero-padding orthogonal frequency division multiplexing (ZP-OFDM) has been proposed as an alternative solution to the traditional cyclic prefix (CP)-OFDM, to ensure symbol recovery regardless of channels nulls.
