Radio-on-FiberSystem Compatible with IP network

我们对同时承载模拟无线电和数字IP信号的副载波复用光纤无线电系统进行了理论和实验研究。以鹿儿岛大学立方体卫星KSAT的地面站为例，提出了一种将400 MHz ~ 13 GHz的射频信号和数字信号进行多路传输的技术，并对每路信号进行了调制和乘法优化。我们对合作者提供的电吸收调制器集成激光器进行了建模，并将其成功地应用于真实的演示系统中。

We performed theoretical and experimental study on a subcarrier- multiplexed radio-on-fiber system that carries both analog radio and digital IP signals simultaneously. Taking an earth station of a Kagoshima University cube satellite, KSAT, as a demonstrator example, we proposed a technique that carriesplural radio-frequency signal of 400 MHz to 13 GHz and digital signal, each of which is optimized for modulation and multiplication. We modeled an electro-absorption-modulator integrated laser, provided by collaborators, and applied it to a real demonstration system successfully.
