Abstract A new method of construction of shift sequences is presented by setting different parameters to shift sequences. With these shift sequences, a class of sequence sets is got with flexible zero or low correlation zone whose set sizes can reach or approach the theoretical bound through interleaving technique, the proposed method can be used to construct more sequence sets suitable for QS-CDMA systems.
