Power Line Communication as a Sensor: Medium Voltage Cable Diagnostics

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This article investigates the use of broadband power line (BPL) communication as a diagnostic tool for medium‐voltage cables. Experimental results show that BPL modem parameters change in the presence of partial discharges, enabling real‐time monitoring of insulation health and supporting predictive maintenance.

Processing and Resolution Losses Due to Range Cell Migration—Application to Automotive Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study analyzes how range cell migration (RCM) affects pulse compression and Doppler processing in high‐resolution radar systems. Theoretical models including RCM effects are developed for both pulse and frequency‐modulated continuous wave (FMCW) radar. Resolution and processing losses are quantified for FMCW, linearly frequency‐modulated (LFM) and

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.
