Notes on period distribution for two classes hamming codes;
关于两类汉明码周期分布的几点注记
The calculation formulae for period distribution of q-ary BCH codes with designed distance 7 were obtained based on the discussion of cyclotomic cosets and property of cyclotomic polynomials: the period distribution is q s power.
通过对循环陪集的研究及利用分圆多项式的一个性质,得到了设计距离为7的q元BCH码的周期分布计算公式:码的周期分布为q的幂,当码的周期不等于某些特殊值时,幂为码长与周期的最大公因数。
The period distribution of q-ary BCH codes is studied by some important theory functions and cyclotomic coset,and the number of non-periodic equivalence classes of q-ary BCH codes with design 5 is given.
利用一些重要的数论函数以及循环陪集,研究了BCH码的周期分布,得到了设计距离为5的q元BCH码的无内周期的码字个数,推广了文献[1]的结果。
