摘要：
In this paper, a phase-coded OFDM signal based on chaos theory for joint radar-communication systems is proposed. The signal has high time-frequency product and flexibility in waveform design. A new approach of getting phase codes from chaotic sequences is introduced, and the new codes own good correlation performance. The peak-to-mean envelope power ratio (PMEPR) and the auto-correlation function (ACF) are two important indexes of the signal PMEPR is decreased to a pretty low level by specific sub-carrier weighing method through systematically research in this paper, while the side-lobe level of ACF of the signal is demonstrated to be relatively low using the sub-carrier complex weight and chaos-based phase code.
