摘　　要：以太网通信是现代社会目前最常用的通信方式之一,其中光缆是一种重要传输媒介。为提高以太网光缆传输数据通信可靠性,实现传输数据误码纠错功能,减小数据传输误码率,提出了基于LDPC码的以太网数据传输编解码。此文结合LDPC编码原理设计出了3种用于以太网数据传输的编码方式即完全串行输出方式,部分并行输出方式以及完全并行输出方式,通过对比分析这3种编码输出方式其资源利用率以及运行速率,发现选用部分并行输出编码方式能够实现性能最优化。Ethernet communication is one of the common communication methods in modern society, and the optical cable is an important transmission medium. In order to improve the optical transmission reliability of data communication, reduce the bit error rate of data transmission, and realize the error correction function of the transmission data, an ethernet data transmission code based on LDPC code is proposed. Combining with LDPC encoding principle, this text completes coding design, and proposes three coding methods for ethernet data transmission, i.e., complete serial output, partial parallel output and complete parallel output. By comparing and analyzing the resource utilization and running rate of the three encoding modes, it is found that the partial parallel output encoding scheme can achieve the optimal performance.
