IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

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

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 ...

Ambiguity Function Optimization Based on Joint Communication and Sensing Waveform
Electronics Letters, Volume 62, Issue 1, January/December 2026.The sidelobe suppression strategy proposed in this study demonstrates significant advantages. Its ability to effectively reduce ambiguity function sidelobes has important practical significance for engineering. ABSTRACT The ambiguity function (AF) plays a critical role in joint communication and sensing (JCAS) systems. In this letter, we design a novel

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 ...
