Abstract: This paper reviews and pre- sents the latest results in the cell search issue of the 3GPP Long Term Evolution (LTE) systems. Cell Search is a basic function of any cellular system, during which process time and frequency syn- chronization between the mobile termi- nal and the network is achieved. Such synchronization is especially important for 3GPP Long Term Evolution systems, which rely heavily on the orthogonality of the uplink and downlink transmis- sion and reception to optimize the radio link performance. As in conven- tional cellular systems, the mobile ter- minal in an LTE system acquires time and frequency synchronization by pro- cessing the synchronization channel. Design of the synchronization channel is being developed within the standard- ization activities of 3GPP Long Term Evolution and is still evolving. In this paper, we present the design considera- tions and various new and promising design concepts for the synchronization channel. We evaluate some specific solutions and provide numerical perfor- mance results.
