几类求值码的对偶性

Duality for Several Families of Evaluation Codes

Maria Bras-Amorós, Michael E. O'Sullivan

摘要:

我们考虑Reed-Muller码,复曲面码和某些平面曲线的码的推广,例如由有限域上的范数和迹函数定义的那些。在每一种情况下,我们感兴趣的代码定义的评估任意子集的单项式,并在识别时的双重代码也获得评估单项式。然后,我们移动到序域理论的上下文中,其中可以使用Berlekamp-Massey-Sakata算法与多数表决来选择单项式的子集以优化解码性能。我们表明,考虑这些子集的代码是良好的行为和对偶代码也定义单项式。

英文摘要:

We consider generalizations of Reed-Muller codes, toric codes, and codes from certain plane curves, such as those defined by norm and trace functions on finite fields. In each case we are interested in codes defined by evaluating arbitrary subsets of monomials, and in identifying when the dual codes are also obtained by evaluating monomials. We then move to the context of order domain theory, in which the subsets of monomials can be chosen to optimize decoding performance using the Berlekamp-Massey-Sakata algorithm with majority voting. We show that for the codes under consideration these subsets are well-behaved and the dual codes are also defined by monomials.
