摘　　要：为了降低光纤链路数据传输量,提出一种采用通用公共无线接口(CPRI)协议的有损I/Q数据压缩方案.采用分组压缩的方式对原始数据进行压缩,用Matlab软件验证该压缩方案的可行性,并用Verilog HDL语言设计压缩模块,在现场可编程门阵列(FPGA)上进行硬件验证.结果表明:文中压缩方案能够有效地压缩数据并恢复数据,降低光纤链路数据传输量.In order to reduce the data transmission volume of optical fiber link,a lossy I/Q data compression scheme base on the common public radio interface(CPRI)protocol was proposed.The original data is compressed by the form of grouping compression,and the feasibility of the compression scheme is verified by Matlab software,and the compression module is designed with Verilog HDL language,the hardware verification is carried out on field programmable gate array(FPGA).The results show that the proposed compression scheme can effectively compress and recover data,reduce the data transmission volume of optical fiber link.
