Cross correlation of m-sequences of different lengths
Geir Jarle Ness, Tor Helleseth · IEEE Transactions on Information Theory · 2006
We consider the distribution of the cross correlation between m-sequences of period 2/sup m/-1, where m=2k and m-sequences of shorter period 2/sup k/-1. We present some general properties of the cross correlation between these m-sequences and we find some decimations with 3-valued cross correlation. We further present some numerical results and open problems.
