近年来，高速无线服务（5G和6G）和可靠传感能力（汽车雷达、空中交通管制、地球物理监测）的增加，导致频谱拥塞更加严重。传统上，雷达和通信系统通常被视为“竞争”相同的资源。在这种情况下，雷达和通信系统的集成平台似乎是解决该问题的最佳解决方案。在本文中，我们提出了一种基于零相关区（ZCZ）和零奇相关区（ZOCZ）序列集的前导码波形设计，这些序列集在多输入多输出（MIMO）雷达中具有多普勒弹性。前导码波形可同时用于 RadCom 系统中的信道估计和雷达感测。所提出的波形的模糊度函数显示时延相关区内的低/零旁瓣。最后，我们给出了一些数值结果来展示所提出的波形在雷达感知和信道估计中的效率。
In recent years, the increased high-rate wireless services (5G and 6G) and reliable sensing capabilities (automotive radar, air traffic control, geophysical monitoring), have led to more serious spectrum congestion. Conventionally, radars and communication systems are often seen to be “competing” for the same resources. In this scenario, an integrated platform for radar and communication systems seems to be an optimal solution to address the problem. In this paper, we propose a preamble waveform design based on zero-correlation zone (ZCZ) and zero odd-correlation zone (ZOCZ) sequence sets, which are Doppler resilient in multiple-input, multiple-output (MIMO) radar. The preamble waveforms can be simultaneously used for channel estimation and radar sensing in RadCom systems. The ambiguity function of the proposed waveforms displays low/zero sidelobes within a time-delay correlation zone. Finally, we give some numerical results to show the efficiency of the proposed waveforms in radar sensing and channel estimation.
