In this paper, we propose three classes of multi-valued signature sequences for direct sequence code division multiple access (DS/CDMA) systems. The first class derived from the two-band perfect reconstruction quadrature mirror filter (PR-QMF) bank has perfect correlation properties when the number of users is two in the DS/CDMA system. The first two classes have perfect correlation properties ...
