摘要: 利用有限域上的迹函数理论和m-序列的迹表示定理, 证明了扩展m-序列的自相关函数是二值的, 同时指出Golomb猜想不能推广到一般有限域GF(qm)上的序列.

关键词: 迹函数, m-序列, 自相关函数

Abstract: The autocorrelation function of generalized m-sequence over GF(qm) is proved to be two-valued, and it is pointed out that one conjecture of Golomb's can't be generalized to GF(qm) .

Key words: trace, m-sequence, autocorrelation function
