DOCSIS MAC層關(guān)鍵模塊的FPGA實(shí)現(xiàn)
[Abstract]:Field Programmable Gate Array (FPGA) has high main frequency and can meet the requirement of high speed data processing. High-end FPGA generally supports several hundred megabytes of frequency and can handle more complex problems because of its stronger ability to process information and more stable operation of the motherboard. The application of FPGA has rapidly expanded from the narrow field of communication infrastructure to a very wide range of applications today. Advances in technology have increased the importance of the Internet in economic development. The availability, quality and competitiveness of broadband services have become and will continue to be key issues in the development of many countries and regions. At present, the bottleneck of the development of broadband network in China lies in the access network, and the key to improve the bandwidth of the network is to improve the bandwidth of the access network. This paper first introduces the characteristics and development of HFC network, and leads to the HFC access technologies EPoC and DOCSIS3.1., which are currently in the forefront of research. Compared with the traditional access technologies, the new generation of HFC access technologies, EPoC and DOCSIS3.1, have higher throughput and higher spectral efficiency, which is the direction of research and development of access technology in the next few years. This paper introduces EPoC and DOCSIS3.1, from the system structure, analyzes their MAC layer protocols and physical layer protocols, discusses the implementation scheme of DOCSIS3.1MAC layer FPGA, focuses on the FPGA implementation of several key modules in the DOCSIS3.1MAC layer, and gives a detailed design scheme. Finally, the test of DOCSIS3.1MAC layer is introduced, and the test results are analyzed.
