摘　　要：本文分析了光波毫米波综合通信的特点，实现了其中关键技术之一的链路性能判决。作者分析了该技术的具体方法，即PN码的产生，快速同步以及利用PN码进行信道监测比较。主要介绍了滑动相关法和随动同步法两种PN码同步的方法，并进行分析比较。通过硬件在FPGA中实现了PN码的随动同步，并且对两路信道的误码率进行监测比较，完成了实物的测试。This paper analyzes the characteristics of the integrated communication of light wave and millimeter wave, and one of its key technologies, the link performance judgment, has been achieved. The author analyzes the specific methods of the technologies, that is the PN code＇s generation, fast synchronization and the signal channels monitoring and comparing by using the PN codes. The author mainly introduces the two kinds of PN code＇s synchronization method of the sliding correlation method and the follow-up syn- chronization method,and further analyzes and compares them. The follow-up synchronization of PN code is realized by means of the hardware in FPGA, and the bit error rate of the two channels is monitored and compared, HDB3 is used for encoding and decoding during the period of signal sending and receiving to complete the system test.
