摘　　要：针对光纤基带传输系统带宽需求不断提升的问题,提出一种I/Q数据压缩方案。该方案结合通用公共无线接口协议(CPRI)的特点,采用分段压缩方式对原始数据进行处理,减少了光纤链路数据传输量和开发成本。通过在FPGA开发板上搭建光纤基带传输电路系统,完成了压缩前后各项性能的指标分析。In order to resolve the growing data volume of base band transmission system based on the fiber, the paper proposes a new method of ]JQ data compression. The new method utilizes the characteristics of CPRI and adopts segmentation compression to deal with the original data, reduces the total amount of trans- ferred data on fiber and the costs of development. The base band transmission circuit system based on the fiber is constructed on the FPGA development board, the performance is analyzed between non-compression and compression.
