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 ...

A Two‐Stage Genetic Algorithm for Joint Optimization of PAPR and PSLR for Precise Signal Reconstruction in OFDM‐ISAC Systems

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 ...

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 ...
