As a key technology for the next generation mobile communication system (IMT-2000), wideband CDMA (W-CDMA) helps users to achieve mobility and interactivity simultaneously. An adaptive transceiver architecture for the uplink W-CDMA system based on the 3GPP radio access network FDD mode specification, with both temporal and spatial diversity is proposed. Scalar channel and vector channel models are both used in the simulation. The channel impairments include 2 kHz carrier frequency offset (1 ppm relative to the 2 GHz RF frequency), -6 dB SNR, 6-ray Doppler fading channel with parameters from the GSM urban outdoors setting in the scalar channel, and 16 rays with different angles of arrival in the vector channel. Simulation results show that the proposed architecture can indeed meet the specified requirement
