A Low-Complexity Synchronization Method for LTE-A System Based on the Symmetric Time Domain Zadoff–Chu Sequence

Recently, Long Term Evolution Advanced (LTE-A) has been widely deployed for the fourth generation wireless communication system due to its high spectral utilization and throughput performance compared with the other systems. LTE-A adopts the Primary Synchronization Signal (PSS), which is generated from the frequency-domain Zadoff–Chu sequence to complete the synchronization and cell search at the receiver. Rather than the full cross-correlation search of the conventional synchronization method, in this paper, we propose a blind and low-complexity synchronization method that utilizes the time-domain symmetric property of PSS sequence. Results show that the proposed method can predict the arrival time and frequency offset of the received signal precisely and has the low-complexity advantage.
