DFT-Spread-Based OTFS Waveform Design With Good Peak-to-Average Power Ratio for Joint Sensing and Communications

We study the problem of orthogonal time frequency space (OTFS) waveform design for joint sensing and communications. Our main objective is to achieve a low peak-to-average power ratio (PAPR) for the OTFS waveform with DFT spread to communication symbols, so that good parameter estimation and bit err…
