Joint Waveform Design for Communication and Sensing with Adjustable PAPR

This paper presents a dual-functional waveform design approach for integrated sensing and communication systems with a base station simultaneously communicating with multiple downlink users and illuminating directions of interest for radar sensing. The joint design goals include matching a desired beam-pattern for sensing and minimization of interference between users for communication, where the trade-off between the two goals is controlled by a tuning parameter. The proposed approach also efficiently integrates practical constraints on per-antenna powers and peak-to-average-power-ratio into the design. Through simulations, we show that the proposed approach achieves lower symbol error rate and better beampattern matching performance compared to the popular baseline state-of-the-art method.
