摘要:
近年来,通信系统日益集成化、小型化、高速化,系统中信号的同址干扰成为影响通信质量的关键因素。为解决这一难题,文章基于微波光子技术,提出了一种射频光传输(ROF)链路,将射频干扰信号放在光域处理,通过链路中构建特定的并联调制结构,使调制到光载波上的两路干扰信号干涉相消,最终实现了超过 60dB 的干扰信号抑制,并且具有光域固有的大带宽、低损耗等优势。
Abstract:
In recent years, the communication system becomes more and more integrated, miniaturized and high-speed. Thus, theco-site interference becomes a key factor affecting the communication quality. To solve the problem, a kind of the radio over fiber (ROF)link is proposed based on the microwave photonic technology in this paper. The radio frequency interference signal is put into the opticaldomain for processing, by building specific parallel modulation link structure, make to the two interference signals in the optical carriermodulation interference cancellation, finally achieved more than 60 dB signal suppression of interference, and it has a light domaininherent advantages of the high bandwidth and low loss.
