Cell Search Procedures in LTE Systems

In this paper, we present a cell search procedure for a Long Term Evolution (LTE) system based device, which involves determining the primary group identifier associated with a cell as well as its timing information. This is facilitated by using the primary synchronization signal available in an LTE system. For the first stage of cell search, this paper presents a time-domain based cell search procedure in an LTE system. Further, we evaluate the performance of such an approach with varying levels of noise and present the design considerations to be utilized in developing a searcher hardware block. We also present analytical and simulation results to evaluate the searcher performance.
