| 摘 要： | 当g(r)是x~n+1的既约多项式,n为奇素数,g(x)是(n,(n+1)/2)循环码C的生成多项式,利用C的对偶码C′生成多项式(x+1)g(x)构造捕错译码器.该方法能提高原捕错译码器的纠错能力,可以识别C(x)中的码型(对偶码和非对偶码)。

| Abstract: | For g(x) is an irreducible factor of xn+ 1, n is odd prime, if g(x) is generatorpolynomial of (n,n+1/2) cycliccode C , then an error-trapping decoder is constructed using 1)g(x) , which is generator polynomial of C' , and.C' is duadic code (n,n-1/2) of C code. The new method can improve error-correcting capability of old Error-Trapping Decoding, and identify form of code C. |

| Keywords: | duadic code error-trapping decoding identify form of code C . |
