Abstract:

A new form of discrete signals, the quaternary sequence pair with threelevel autocorrelation, is proposed. The quaternary sequence pairs with even period is studied. The maximum out-of-phase autocorrelation is at least two is gotten, which has the character of any quaternary sequence pairs with even period and three-level autocorrelation. A construction of quaternary sequence pairs with even period and the autocorrelation value of {0,-2} is presented. And the balanced quaternary sequence pairs with optimal autocorrelation values can be obtained if the used pseudorandom binary sequence pairs have the optimum properties of balance.
