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 1012, so the method is effective and fits the system require.关键词
