Binary Sequence Pairs of Period p^m-1 with Optimal Three-Level Correlation

抄録

Let F_pm be the field of p^m elements where p is an odd prime. In this letter, binary sequence pairs of period N=p^m-1 are presented, where sequences are generated from the polynomial x²-c for any c ∈ F_p^m\{0}. The cross-correlation values of sequence pairs are completely determined, our results show that those binary sequence pairs have optimal three-level correlation.
