Abstract
To solve the problem of low estimation accuracy for orthogonal frequency division multiplexing (OFDM) fractional frequency offset (FFO) over multipath channels in non-cooperation communication system, a novel blind estimation of OFDM FFO is conceived. The starting position of data sampling points without inter-symbol interference is estimated in the cyclic prefix, and then the frequency offset is estimated by adopting the maximum likelihood criterion. The simulation results demonstrate that the proposed method has better performance than traditional methods, so it is applicable to the noncooperation communication systems.
