EPON系统中的FEC译码算法实现比较

Introducing the FEC technique into EPON system, can contribute to a significant increment in both the splitter number of PON and the transmitting distance of signals. Since the characteristics of the FEC code used in the EPON system determine high complexity of the algorithm of coding, choosing a proper algorithm of coding, which is low in both time complexity and space complexity, appears to be a worthwhile researching direction. In this text, by contrasting the complexity of two mainstream algorithms, the authors eventually find an efficient algorithm of coding, which is suitable for being actualized by FPGA and sensitive to capability and scale.
