Digital Mobile Communication Systems are prevalent worldwide for providing data/voice services. Second generation systems are limited to the maximum data rate they can support. Third generation Mobile communication systems provide more advanced services such as broadband internet access, video telephony and video conferencing services. It integrates a wide variety of communication services such as high speed data, video and multimedia traffic as well as voice signals. In the Third Generation (3G) Cellular Systems, one of the most important and complex parts in the receiver is a carrier synchronization unit. The data is transmitted in a frame by frame basis through a time varying channel. The phase and frequency of the transmitted signal may also be shifted because of fading and the Doppler frequency shift. In receiver side, carrier frequency of the receiver should be synchronized with the incoming signal. In this paper, we designed, low complexity, adaptive baseband receiver carrier synchronization architecture for uplink wide band code division multiple access (WCDMA) system based on 3rd Generation Partnership Project(3GPP) radio access network Frequency Division Duplex (FDD) mode specification and its Field Programmable Gate Array ( FPGA) Simulation is presented.
