本文提出一种最小距离为6的纠检错码,适硬于采用8位微型机的遥测遥控糸统进行自动回询纠错(ARQ)或前向纠错与自动回询纠错混合(HEC)的数据传输。文中给出了检5错和纠1检4错的译码方案。在 Z-80机上用汇编语言编程实现编码和译码表明,在编译码程序所占内存约为1 K 字节的情况下,传输速率可达48kb/s。
In this paper, we propose an error correction code with a minimum distance of 6, which is suitable for ARQ or forward error correction and auto-query error correction hybrid (HEC ) Data transfer. The article gives the detection of 5 wrong and correct 1 check 4 wrong decoding scheme. Encoding and decoding using assembly language programming on a Z-80 machine shows that the transfer rate can be up to 48kb / s in the case of a program memory of about 1 kilobyte.
