摘要
Considered is the distribution of the cross correlation between m-sequences of length 2(m) - 1, where m = 2k, and m-sequences of shorter length 2(k) - 1. New pairs of m-sequences with three-valued cross correlation are found and the complete correlation distribution is determined. Finally, we conjecture that there are no more cases with a three-valued cross correlation apart from the ones proven here.
