【摘要】 提出了一个基于HDLC协议的CPRI慢速控制管理信道的实现方法。采用HDLC协议封装控制管理命令,然后把经过HDLC封装的控制管理命令跟CPRI其他数据时分复用在一条物理链路上。对于上层控制管理实体,相当于在两端建立了一个直接传输控制管理命令的虚拟通道。重点描述了CPRI控制管理信道实现的关键部分HDLC协议在FPGA中的设计与实现,采用了自顶向下的方法将设计细化为若干个模块,并对设计的各个模块进行了仿真和测试。通过验证表明:采用HDLC协议成功实现了CPRI控制管理信道。更多还原

【Abstract】 An implementation of CPRI Control and Management channel based on HDLC is proposed.It uses HDLC to encapsulate Control and Management data,and then time-division multiplexes the Control and Management data encapsulated on a physical link with other CPRI data.For the upper Control and Management entity,it is equivalent to establish a virtual channel directly transferring Control and Management data at both ends.The design and implementation of HDLC protocol in Field Programmable Gate Array(FPGA) which is the key part of implementation of CPRI C&M channel is described.Using the"Top to Down"method,the design is divided into several functional modules,which are emulated and tested.Through the verification:CPRI Control and Management channel based on HDLC is implemented successfully.更多还原
