| 摘 要： | 设计了一种基于FPGA的RRU光口与微波传输系统IDU之间的转换接口,在下行方向上,将近端RRU光口基于CPRI协议的光信号按照文中所提出的传输协议转换为STM-1速率的信号,使之与微波SDH传输速率相匹配,上行方向则进行相反的过程.实验室测试结果表明,该方法切实有效,传输时延为49μs左右,且误码率小于10-12,满足系统的整体指标要求.

| Abstract: | This paper introduces a convertible interface between RRU and IDU based on FPGA technology.On the down link,the optical signal from the interface of local RRU based on CPRI protocol is converted into STM-1 signal according to the transmission protocol,then made match with SDH speed.On the up link,the whole process is opposite.The transmission delay is 49us and BER is less than 10-12,so the method is effective and fits the system require. |
