摘　　要：提出了一种改进的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)载波频率偏移估计算法并通过MATLAB进行仿真。仿真结果表明算法对小数载波频率偏移估计精度高并且其算法复杂度低。An improved algorithm for the carrier frequency offset estimate in an OFDM system is proposed and simulated by using MATLAB. The results show that it has a higher estimate precision and a lower complexity for the OFDM system with the fractional carrier frequency offset.

关 键 词：OFDM 频率偏移估计 迭代
