基于单片机的扩展汉明循环码的设计

The Design of Expansion Cyclic Hamming Code Based on MCU

给出了一种扩展汉明循环码的实现方案,它的特点是在编译码时把循环码和奇偶校验位分开处理,使得能用比较简单的电路实现纠正1位错同时检测2位错的译码要求。并且给出了在STC12C5A60S2单片机上的实现过程。

This paper realizes expansion of the function of checking and rectification for the Hamming codes by using the extended Hamming codes.This design makes use of MSC-51.The results prove that the expansion coding and decoding methods improve the reliability of data transmission without increasing the hardware markedly,which has much actual significance.
