摘要

IEEE标准802.3第74节介绍了一种缩短循环码(称为前向纠错[FEC]),旨在提高链路预算和误码率(BER)性能。FEC广泛应用于10G/40G以太网等高速服务器通信应用中。本文提出了一种快速检测接收码块边界的芯片同步算法。与802.3标准中概述的算法相比,该算法将同步时间提高了三个数量级。

Fast synchronization algorithm for the Forward Error Correction in IEEE Standard 802.3
A shortened cyclic code (known as Forward Error Correction [FEC]) aimed at increasing link budget and Bit Error Rate (BER) performance is introduced in section 74 of IEEE Standard 802.3. FEC is widely used in High Speed Serdes communication applications like 10G/40G Ethernet. This paper proposes a synchronize algorithm for chip implementation which quickly detect the boundary of the received code block. Compared with the algorithm outlined in the 802.3 standard, the proposed one improves synchronization time by three orders of magnitude.
