Even period quaternary sequence pair with three-level autocorrelation
Li Gang · Systems engineering and electronics · 2012
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.
