- W2355305025 abstract "Time and frequency synchronization is the core module of the terminal cell search process;its performance will affect the performance of demodulation system directly.Based on the research on cell search time and frequency Synchronization algorithm in TD-LTE system,according to the secondary synchronization signal(SSS) sequence character,a timing and frequency synchronization algorithm based on SSS is proposed in this paper.The center of symmetry conjugate point for SSS signal could be estimated according to the conjugate symmetry in time domain of SSS signal,and then the timing synchronization can be obtained.At the same time,the fractional frequency offset is estimated corresponding to the timing position of the fractional frequency offset calculation results.The properties of the algorithm are simulated and analyzed in the MATLAB,the simulation results show that SSS timing synchronization algorithm can resist the impact of large carrier frequency offset on timing synchronization performance.From the calculation process,the algorithm only uses the symmetric multiplication of the received signal to estimate the frequency offset estimation,which greatly reduces the computational complexity.The algorithm's performance is perfect and complexity is low,and it improves the reliance in comparison with the normal methods." @default.
