The receiver uses multi-channel reception and data processing technology to achieve fast capture and tracking of frequency hopping signals. Specifically, the system uses a frequency synchronization module to perform rough frequency correction on the received signal, and uses a COSTAS loop for detailed phase synchronization. Then, the system uses a multi-channel structure to capture and track the frequency hopping signal, achieving fast switching between different emitters. Finally, the system uses a de-spreading module to perform de-spreading processing on the received data, improving the reliability of the received data. Experimental results show that the system has the advantages of fast capture, stable tracking, and high reliability, and can be used in military communications, satellite communications and other fields.Keywords: Hopping communication system; receiver; multi-channel; COSTAS loop; de-spreading module一、讨论背景随着通信技术的不断进步，跳频通信系统已经成为一种重要的通信方式。跳频通信系统具有频谱扩展、抗干扰等优点，因此被广泛应用于精品文档---下载后可任意编辑军事通信、卫星通信等领域。而在...
