摘　　要：随着信息技术对通信系统的容量、带宽、安全性以及灵活性的要求越来越高,当今通信网络逐渐不能满足这种需求,光载毫米波系统已经成为目前国内外的研究热点。通过理论建模,在光载毫米波信号系统的发送端利用两平行的马赫-曾德尔调制器分别对两射频信号进行调制,经过长距离的光纤传输之后,在接收端利用两个光电探测器分别进行探测,通过仿真在接收端同时产生了两束高质量的毫米波信号,并得到了解调之后的基带信号的眼图。With the development of information technology, it requires more power for the capacity, bandwidth, security and flexibility of the communication system. However, the communication network today gradually can＇ t meet this need, so the radio over fiber system has become a research hotspot at home and abroad. Through theoretical modeling, two RF signals are modulated respectively by using the two parallel Mach-Zehnder Modulators on the transmitting side of the radio over fiber system. After a long-distance optical fiber transmission, the signals are detected by using two photodetectors to on the receiving end. The two high quality beams of millimeter wave signals are produced by simula- ting. In the meanwhile, the eye diagram of the demodulation baseband signal is obtained.
