WebAn order O ˆK in a number eld K is a subring of K which is a lattice with rank equal to deg(K=Q). We refer to [17, 18, 7] for number theoretic properties of orders in number elds. Let ˘ nbe a primitive n-th root of unity, the n-th cyclotomic polynomial nis de ned as n(x) = Q n j=1;gcd(j;n)=1 (x ˘ j n). This is a monic irreducible WebIn order to construct cyclic codes, Ding described a new generalized cyclotomy V 0, V 1, which is a new segmentation of the Ding–Helleseth generalized cyclotomy of order two . By use of this cyclotomic class, Liu et al. constructed a generalized cyclotomic sequence . Let the symbols and the functions be the same as before.
