Modification of Synthetic Filtered Output for PSL Reduction in DFT‐Spread OFDM MIMO Radar Using Doppler‐Tolerant Extended Space‐Time Coding

Electronics Letters, Volume 62, Issue 1, January/December 2026.
We propose a Doppler‐tolerant DFT‐spread orthogonal time‐coded OFDM (DSS‐OTC‐OFDM) waveform for MIMO radar that maintains orthogonality under Doppler shifts while enabling flexible code design. An optimisation framework is developed to minimise peak sidelobe level (PSL) and suppress cross‐correlation after matched filtering across a range of Doppler ...

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.

Two Types of Mixed Orthogonal Frequency Division Multiplexing (X-OFDM) Waveforms for Optical Wireless Communication

IEEE Transactions on Wireless Communications, 2022
The optical wireless communication (OWC) with the intensity modulation (IM), requires the modulated radio frequency (RF) signal to be real and non-negative. To satisfy the requirements, this paper proposes two types of mixed orthogonal frequency division multiplexing (X-OFDM) waveform.

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

Circuit‐Theoretic Modeling and Simulation Study of Near‐Field MIMO Arrays of Dipole Antennas

Active and Passive Electronic Components, Volume 2026, Issue 1, 2026.
Near‐field mutual coupling among closely spaced antennas limits the deployment of wireless MIMO interconnects in chip‐to‐chip communication. This paper presents a circuit‐theoretic modeling and simulation study of near‐field MIMO (NFMIMO) systems using 1 × 1 and 2 × 2 dipole arrays.

Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom

IEEE Access, 2019
In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...
