A new scheme for initial cell search in time division long term evolution systems

Abstract

Initial Cell Search is a process that User Equipment (UE) adopts to reside to a cell, and its performance has a direct impact on the follow-up process of UE. However, the efficiency of conventional initial cell search in which UE has a Broadcast Control Channel Allocation (BA) table is low. Therefore, this paper presents a correlation algorithm to speed up the UE cell search with a BA table. Simulation results show that the new scheme can reduce the time-consuming of UE and decrease the probability of error frequency points in the initial cell search.
