    In this paper we propose the multimedia communication on direct sequence CDMA system and implement it by using Wavelet technique. It is an analysis tool for time frequency localization. In this paper we choose Morlet as the mother wavelet yielding Gaussian shape in frequency spectrum. Another advantage of Gaussian shape can reduce the sidelobe powers of the frequency spectrum result in efficient frequency bandwidth. The evaluations of the performance are proposed and compare with the conventional CDMA system.
