Universal Filtered Multicarrier (UFMC) vs. Orthogonal Frequency Division Multiplexing (OFDM)

Journal of Physics: Conference Series, 2020
Abstract Wireless systems can be utilized in various areas. These wireless systems require a flexible mechanism for the allocation of the available time and frequency resources. The framework time-recurrence designation is very troublesome in the regular OFDM frameworks. The multicarrier procedure has been a dumbfounding technique in the

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.

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 ...

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

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]

, 2009
At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

A DFT-Based Scheme for PAPR Reduction in SR-OFDM Systems

IEEE Access
This paper focuses on the peak-to-average power ratio (PAPR) reduction in symbol repetition-based orthogonal frequency division multiplexing (SR-OFDM) systems, and a discrete Fourier transform (DFT)-based scheme is proposed to reduce the PAPR of SR-OFDM ...

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.
