Learning to Precode for Integrated Sensing and Communication Systems

open access: yes2023 31st European Signal Processing Conference (EUSIPCO), 2023
In this paper, we present an unsupervised learning neural model to design transmit precoders for integrated sensing and communication (ISAC) systems to maximize the worst-case target illumination power while ensuring a minimum signal-to-interference-plus-noise ratio (SINR) for all the users. The problem of learning transmit precoders from uplink pilots
