智能交通系统(ITS)中的无线车对车(V2V)通信和汽车雷达的频谱共享可以提供更高的频谱利用效率。然而,两个系统之间的频谱共享可能会带来严重的干扰,这需要很好地解决。为了解决通信雷达频谱共享(CRSS)和系统间干扰的问题,我们首先建模的雷达干扰估计为离网压缩感知问题。然后,我们提出了一种基于原子范数(AN)最小化理论的干扰消除算法。仿真结果表明,该算法实现了雷达与通信的共存,有效提高了车载雷达干扰下的V2V通信性能。
Spectrum sharing of wireless vehicle-to-vehicle (V2V) communication and automotive radar in intelligent transportation systems (ITS) can provide higher spectrum utilization efficiency. However, spectrum sharing between two systems might bring severe interference, which needs to be well solved. To address the communication-radar spectrum sharing (CRSS) and inter-system interference issue, we first model the radar interference estimation as an off-grid compressed sensing problem. Then, we propose an interference cancellation algorithm based on the atomic norm (AN) minimization theory. Simulation results show that the proposed algorithm facilitates the coexistence between radar and communication and improves the V2V communication performance efficiently in the presence of automotive radar interference.
