The optimal discrete signal are widely used in spread spectrum communication systems, sonar, navigation, code division multiple access systems and other fields. The perfect sequence pair is an extension of the single best signal, so its application is more widely. This paper puts forward new methods of constructing the binary sequence pair of three values and quaternion sequence pair of three values according to the problem of constructing the sequence pairs of three values. This method is that it uses N long cyclotomic pseudo-random sequence and its shift sequences pair to do series connection to constitute a 4 N long binary sequence pair of three values. New sequence pairs of three values is obtained by this method proved to have good balance. The application steps of this method are given and shall be verified by some examples.
