EURASIP Journal on Wireless Communications and Networking, 2004 Multiple-access interference and interfinger interference limit the capacity of conventional single-carrier DS-CDMA systems. Even though multicarrier CDMA posses the advantages of conventional CDMA and OFDM, it suffers from two major implementation ...

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.Mixed halide perovskites suffer from photo‐induced phase segregation, leading to compositional instability and degraded device performance. This review summarizes the dynamic behavior and kinetics of phase segregation in thin films under external stimuli, analyzes compositional and environmental effects, and proposes suppression strategies to enhance ...

IET Communications, Volume 20, Issue 1, January/December 2026.This work extends the Polyanskiy‐Poor‐Verdu (PPV) framework to lognormal wireless links. Specifically, the paper derives a closed‐form approximation for the average error probability under lognormal distribution, effectively generalizing the PPV analysis beyond the additive white Gaussian noise assumption.

Unified Downlink‐Uplink Waveform Optimization For MIMO‐OFDM Integrated Sensing and Communication
IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a unified waveform allocation framework for downlink and uplink MIMO‐OFDM integrated sensing and communication (ISAC) systems in 6G networks. We develop five optimization schemes, including optimal‐for‐communication, optimal‐for‐sensing, and MMSE‐based joint allocation, with closed‐form expressions for spectral efficiency, sensing ...
