摘要: 首先, 针对子空间轨道长度与子空间多项式指数之间联系的结论, 给出一较简洁的证明; 其次, 通过对子空间做Frobenius移位与合并循环子空间码, 得到码字个数更多((rn(qN-1)/(q-1))、 极小距离为2k-2的循环子空间码; 最后, 给出构造循环子空间码的实例.

关键词: 循环子空间码, 子空间多项式, Frobenius移位, 轨道

Abstract: Firstly, we gave a relatively concise proof concerning the relationship between the length of subspace orbits and the exponent of subspace polynomials. Secondly,  by applying Frobenius shifts to subspaces and merging  cyclic subspace codes, we obtained cyclic subspace codes with a larger size of ((rn(qN-1)/(q-1)) and a minimum distance of 2k-2. Finally, we gave an example of constructing a cyclic subspace code.

Key words: cyclic subspace code, subspace polynomials, Frobenius shift, orbit
