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 ...
