With the increasing demand for sensing functions in the 6-th generation (6G) wireless communication networks, waveform design has become critical. The waveform must ensure a high quality of service in communication and achieve high precision in sensing; thus, interference between these two functions should be minimized. This paper proposes a power division waveform design for integrated sensing and communication (ISAC) based on orthogonal frequency division modulation (OFDM). This waveform design utilizes the Zadoff-Chu (ZC) sequence as the symbol sequence for sensing. The probability of detection for this method can reach approximately 0.8. The properties of the ZC sequence make it easy to implement in LTE and NR base stations and allow it to be effectively eliminated through successive interference cancellation. Additionally, the potential of this waveform in channel estimation (CE) is also analyzed, demonstrating an accuracy of CE under 3.5 × 10−3.
