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.
