An Optimal-frequency Select Algorithm in Vehicle Electromagnetic Compatibility Design

针对车载通信系统中多个无线通信设备同时工作导致的电磁干扰问题,论文通过分析发射机的基本频率、谐波频率和接收机受损频带之间的关系,提出一种优选工作频率的算法。实例测试与理论分析结果表明该算法可以保证系统的整体通信性能,并有效提升高负载频谱系统的电磁兼容指标。

To resolve the electromagnetism jam in vehicle communication system when a few wireless communication devices run simultaneously,we introduce an optimal frequency select algorithm based on the relationship between the base frequency,the harmonic wavelength frequency of the transmitter and the injured frequency band of the receiver.The actual device test and the theoretical analysis proved that the employ of the algorithm can guarantee the performance of the system and improve the electromagnetic compatibility level,especially in high frequency load application.
