同时传输无线和有线业务的光纤无线通信系统研究

Study on ROF Systems Providing both Wireless and Wired-Line Services

提出了一种新的同时传输有线业务和无线业务并能实现波长重用的ROF通信系统,而且通过系统仿真证实了系统可行性.基于MZM调制器的光载波抑制方式产生毫米波,这样有线、无线信号就共享同一传输信道,充分利用了通信带宽,也大大减少了通信的成本,而且实现了波长重用,简化了基站设计,降低了基站成本,提高了混合网络的实用性.

A simple and efficient ROF systems providing both wireless and wired-line services with wavelength reuse,have been designed.The feasibility of the system through system simulation is confirmed.We employed MZM to modulate the wired-line data on the centre carrier using Intensity Modulation（IM）,the wired-line and the wireless signals on only one optical wavelength in this program is modulated,it greatly reduced communication costs and made good use of the communications bandwidth.
