摘要:

在高速链路的可靠传输中,物理层前向纠错的研究主要集中在提高编码的纠错性能,且编码冗余位全部用于纠错校验,难以满足用户在传输中加载定制信息的应用需求。针对这一问题,设计了一种编码利用率更高、灵活性更强的前向纠错编码方案,并通过Matlab和综合工具对性能和开销进行了评估,在不损失编码性能的前提下得到了一系列可以无损加载用户定制信息的前向纠错编码。

Abstract:

In the reliable transmission of highspeed links, research of forward error correction (FEC) in physical layers focuses on improving error correction coding performance. The fact that all coding redundancy is used for error correction leaves no margin to load usercustomized information in transmission. Thus, we design an enhanced FEC coding scheme with higher coding efficiency and greater flexibility. The coding performance and cost are evaluated by the Matlab and synthesis  tools. FEC codes are capable of loading usercustomized information with no additional cost or harm to coding performance.
