摘要：
This paper designs a low peak-to-average power ratio (PAPR) Integrated Sensing and Communication (ISAC) waveform based on OFDM. Firstly, we propose an ISAC waveform structure, in which radar subcarriers within the OFDM symbols are randomly located anywhere within non-contiguous Physical Resource Blocks (PRBs). Using this OFDM-based ISAC waveform structure, the sensing mutual information (MI) between the radar channel and the received waveform is derived and maximized under the constraints of communication data information rate (DIR), PAPR, and transmit power. Then, an optimization algorithm is proposed to obtain the optimal power allocation of subcarriers. Finally, simulation results verify the effectiveness and flexibility of our designed waveform.
