摘要

In this paper, let n=2k and d=3⋅2k−2 with k≥3 and gcd(d,2n−1)=1 . Based on some analysis of certain equations over finite fields and the number of codewords with Hamming weight five in Zetterberg code, the correlation distribution between a binary m -sequence of period 2n−1 and its d -decimation sequence is completely determined. This solves a ten-year-old open problem proposed by Dobbertin et al.
