A New Three-Valued Cross Correlation Between$m$-Sequences of Different Lengths
Geir Jarle Ness, Tor Helleseth · IEEE Transactions on Information Theory · 2006
The distribution of the cross correlation between m-sequences of period 2m-1, where m=2k, and m-sequences of shorter period 2k-1 is considered. A new pair of m-sequences with three-valued cross correlation is found and the complete correlation distribution is determined
