论文摘要
频率跳跃（FH）关节雷达通信（JRC）可以为集成感应和通信系统提供出色的安全性。但是，现有的JRC方案主要仅使用子脉冲频率嵌入信息，因此数据速率受到限制。在本文中，我们建议同时使用子脉冲频率和持续时间进行信息调制，从而导致更高的通信数据速率。为了进行信息解调，我们通过使用时频分析（TFA）技术和“您只看一次”（YOLO）（YOLO）的检测系统提出了一种新的方案。因此，我们的系统不需要通道估计，从而简化了传输信号框架设计。仿真结果证明了我们方案的有效性，并表明它对多普勒偏移和收发器和通信接收器之间的时机偏移是鲁棒的。
Frequency-hopping (FH) joint radar-communications (JRC) can offer excellent security for integrated sensing and communication systems. However, existing JRC schemes mainly embed information using only the sub-pulse frequencies and hence the data rate is limited. In this paper, we propose to use both sub-pulse frequencies and durations for information modulation, leading to higher communication data rates. For information demodulation, we propose a novel scheme by using the time-frequency analysis (TFA) technique and a "you only look once" (YOLO)-based detection system. As such, our system does not require channel estimation, simplifying the transmission signal frame design. Simulation results demonstrate the effectiveness of our scheme, and show that it is robust against the Doppler shift and timing offset between the transceiver and the communication receiver.
