In a Code Division Multiple Access (CDMA) system, a lot of users use concurrently the entire frequency band to transmit their data and users' data is separated on the basis of their unique spreading code. The aim of communication system i.e. Communication at anytime, anywhere and by anybody is still not fulfilled but the technology like CDMA can fulfill the aim of communication system if it is properly analyzed. For a downlink transmission Quadrature Amplitude Modulation (QAM), Quadrature Phase Shift Keying (QPSK) and Binary Phase Shift Keying (BPSK) modulation techniques are considered in a Wideband Code Division Multiple Access (WCDMA) system.
