| 摘 要： | 为了获取数字通信中未知线路的纠错编码信息,提出了一种RS码快速盲识别方法.通过对RS码的二进制表示进行码根求解的方法来检测未知线路的RS码长、本原多项式阶数以及可能的本原多项式;进而遍历得到的本原多项式对RS序列进行伽罗华域的傅里叶变换(GFFT),通过连零位置和个数最终确定未知线路的真实本原多项式和生成多项式.实验验...

| Abstract: | In order to get the error-correcting coding information of the unknown lines in digital communication,a fast blind recognition method of Reed-Solomon(RS) coding is presented.RS coding length,the order of the primitive polynomial and the possible primitive polynomials were detected by seeking the roots of binary form of RS codes.The true primitive polynomial and generator polynomial of the unknown line were gained by the position and number of the connective zeros in the Galois Fields Fourier Transform(GFFT)... |
