摘要
基于GF(2m )域的傅里叶变换和傅里叶反变换,提出了Reed-Solom on(R-S)系统码的一种变换域译码算法,并用C语言予以实现.与常规R-S译码算法相比,该算法运算规范,具有不用求错误多项式的根和错误值、硬件开销小、吞吐率高等优点,适合超大规模集成电路的实现.
A transform field decoding algorithm of R\|S systematic code based on Fourier theory and it is implemented by using c language.Contrast to ordinary R\|S decoding algorithm,our algorithm operates criterion,it has character that it doesn't extract the root and value of error polynomial,and is adapt to be implemented by VLSI.
