摘要
分析汉明码与循环冗余校验 (CRC)的特性 ,提出了一种运用此两种方式相结合的差错控制编译码方案。用硬件描述语言 VHDL 进行功能描述与仿真结果表明 ,此种方法可以纠正单个码组中的一位错码并能检测出多位错码。最终在现场可编程门阵列 (F PGA)上实现。
Analyzed the characteristic of Hamming code and CRC, using the combination of this two ways to realize an error control codingdecoding method. Some description and simulation based on hardware description language VHDL is also done which reinforced the result that this method have the capacity of correcting one and detecting some wrong codes in a single code grope. And last we carried out the project on FPGA.
