m-sequences of different lengths with four-valued cross correlation
Tor Helleseth, Alexander Kholosha, Aina Johanssen · 2008
Considered is the distribution of the cross correlation between m-sequences of length 2m-1, where m is even, and m-sequences of shorter length 2m/2-1. The infinite family of pairs of m-sequences with four-valued cross correlation is constructed and the complete correlation distribution of this family is determined.
