Abstract
This paper focuses on shortening the mean time to acquire for initial cell search in the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system. Exact result of mean time of the cell search is obtained by use of a state transition diagram of discrete-time Markov process for the acquisition process. From the deduced mean time formula, it can be seen that the false alarm probability plays a more important role in the acquisition time performance. In order to perform the initial cell search quickly, a new PSS detection structure which includes a verification module to suppress the false alarm is developed. Simulations show that the new structure can decrease the false alarm probability, and reduce the total acquisition time especially in the low SNR circumstance.
