论文摘要
我们提出了一种新的方法来解决具有可调峰与平均功率比(PAPR)(PAPR)的双功能雷达和通信(DFRC)波形设计,同时最大程度地降低了多用户通信干扰并维持对雷达chirp信号的相似性约束。该方法适用于通用雷达chirp信号和不同的星座大小。我们将波形设计问题提出为非凸优化问题。作为解决方案,我们采用了乘数的交替方向方法(ADMM),因此以雷达和通信目的朝着稳定的波形迭代。此外,我们证明了所提出的方法的收敛性并分析其计算复杂性。此外,我们提供了该方法的扩展版本,以应对不完美的通道状态信息(CSI)。最后,与最先进的雷达通信波形设计相比,我们通过模拟证明了它的出色性能。
We present a novel approach to the problem of dual-functional radar and communication (DFRC) waveform design with adjustable peak-to-average power ratio (PAPR), while minimizing the multi-user communication interference and maintaining a similarity constraint towards a radar chirp signal. The approach is applicable to generic radar chirp signals and for different constellation sizes. We formulate the waveform design problem as a non convex optimization problem. As a solution, we adopt the alternating direction method of multipliers (ADMM), hence iterating towards a stable waveform for both radar and communication purposes. Additionally, we prove convergence of the proposed method and analyze its computational complexity. Moreover, we offer an extended version of the method to cope with imperfect channel state information (CSI). Finally, we demonstrate its superior performance through simulations, in comparison to state-of-the-art radar-communication waveform designs.
