纠两个错的二元戈帕码的完全译码算法
AN ALGORITHM OF COMPLETE DECODING OF DOUBLE-ERROR-CORRECTING GOPPA CODES
-
摘要: 本文给出生成多项式G(z)=z2+z+、具有参数(2m,2m-2m,5)的纠两个错的二元戈帕(Goppa)码完全译码的一个算法。这个算法最多只需要m次计算GF(2)上m维向量的内积和解GF(2m)上二次方程的根,就可实现完全译码。对m12,本文的算法已在IBM-PC机上实现。

Abstract: In this paper an algorithm of complete decoding procedure for the Goppa codes with generator polynomial G(z)=z2+z+ and parameters (2m, 2m-2m, 5) is shown. The algorithm requires at most m times calculatng inner product of vectors over GF(2) and finding roots of quadratic equation in GF(2m). Por m 12, the algorithm has been realized. -
