摘要
该文提出了一种基于FFT的联合帧同步和频偏估计算法,可有效地消除频偏对帧同步性能的影响,频偏估计范围可达一只。／2～Rs／2。计算机仿真表明,当存在频偏时,该算法的帧同步性能优于目前已知算法的性能。
This paper presents a new combined algorithm based on FFT for frame synchronization and frequency offset estimation. The algorithm can achieve frame synchronization effectively in the presence of a frequency offset and the frequency offset estimation range is -Rs/2-Rs/2. Simulation results indicate that the proposed algorithm can outperform existing methods when a frequency offset exists.
