摘要:

在本文中,我们开发了一种预测波束形成方案的基础上的双功能雷达通信(DFRC)技术,其中路边的单位估计的运动参数的车辆利用DFRC信号的回波。与传统的基于反馈的波束跟踪方法相比,该方法可以减少信令开销,提高跟踪性能。提出了一种新的消息传递算法,该算法通过最大后验估计获得了接近最优的性能。仿真结果表明了所提出的DFRC方案的有效性。

英文摘要:

In this paper, we develop a predictive beamforming scheme based on the dual-functional radar-communication (DFRC) technique, where the road-side units estimates the motion parameters of vehicles exploiting the echoes of the DFRC signals. Compared to the conventional feedback-based beam tracking approaches, the proposed method can reduce the signaling overhead and improve the tracking performance. A novel message passing algorithm is proposed, which yields a near optimal performance achieved by the maximum a posteriori estimation. Simulation results have shown the effectiveness of the proposed DFRC based scheme.
