摘要
为了开发数字直放站连接系统,介绍CPRI协议规范和帧结构,讨论其硬件上的实现方案,给出基于SCAN25100的FPGA电路模块设计,采用Verilog语言设计开发功能模块。该方案具有便于功能扩展、成本低、使用灵活等特点,通过实际测试表明,此方案可进行可靠的数据传输,性能稳定,从而实现了数字直放站和基站之间更有效的互通,扩大了基站的覆盖范围。
To develop the connection of digital repeaters, CPRI protocol specification and frame structure are introduced. Its implementation on hardware is discussed. The detail module design of FPGA circuit and program based on SCAN25100 are elaborated. The design is easy to expand and low cost. The experimental analysis shows that the solution could accomplish the data transmission, and the interconnection between base station and digital repeater are implemented, the network＇s coverage is enhanced.
