Abstract
In this paper, we propose a novel frequency synchronization method in 3GPP long term evolution (LTE) system downlink for both frequency division duplex (FDD) and time division duplex (TDD) modes. The proposed method includes coarse frequency offset estimation (FOE) using primary synchronization signal (PSS) based correlation in time domain, and fine FOE using phase difference between PSS and secondary synchronization signal (SSS) in frequency domain. Traditionally, cyclic prefix (CP) based method is widely used for fine FOE which is however sensitive to the time synchronization error and multi-path fading channel environment. The proposed fine FOE shows an apparent advantage in both FDD and TDD modes compared with CP based method. In addition, both theoretical analysis and simulation results show that the proposed fine FOE in TDD mode outperforms that in FDD mode under the same system assumptions. The simulations are done under a dual-cell scenario where there is co-frequency interference from the adjacent cell.
