摘要
从信道纠错编码的基本思想出发,讨论了汉明码、扩展汉明码以及交织的纠错检错能力,提出了对扩展汉明码进行交织重排的算法。然后采用C语言对该算法进行程序设计,验证了该算法的可行性。结果表明:此种算法具有较强的抗干扰能力,提高了传输数据的可靠性。
On the basic principle of channel error-control coding theory, the ability of detecting and correcting errors was discussed between Hamming code and extended Hamming code, then the principle of interlace and rebuild of extended Hamming code was introduced. Programs were written in C language to demonstrate and prove the algorithm. The results prove that the algorithm of interlace and rebuild of extended Hamming code has robust ability of anti-disturbing to enhance the reliability of data transmission.
