论文摘要
我们考虑了用于关节雷达和通信（JRC）系统的基于多载波CHIRP的波形，并得出其时间离散的周期性歧义函数（AF）。波形的一个优点是它包含一组波形参数（例如，chirp速率），这些参数与发射序列一起选择，可以选择以灵活形态形成为thumbtack样的AF，或沿延迟轴或多普勒轴类似脊状的。这些形状适用于不同的用例，例如目标检测或时间频率同步。结果表明，在具有较大多普勒频率的通道上，可以实现比OFDM和DFT-S-OFDM更好的信号检测性能。此外，显示如何选择传输序列，以实现波形的0 dB峰值到平均水平比率（PAPR）。
We consider a multicarrier chirp-based waveform for joint radar and communication (JRC) systems and derive its time discrete periodic ambiguity function (AF). An advantage of the waveform is that it includes a set of waveform parameters (e.g., chirp rate) which together with the transmit sequence, can be selected to flexibly shape the AF to be thumbtack-like, or to be ridge-like, either along the delay axis or the Doppler axis. These shapes are applicable for different use cases, e.g., target detection or timeand frequency synchronization. The results show that better signal detection performance than OFDM and DFT-s-OFDM can be achieved on channels with large Doppler frequency. Furthermore, it is shown how transmit sequences can be selected in order to achieve 0 dB peak-to-average-power-ratio (PAPR) of the waveform.
