A Frequency Offset Estimation Algorithm Based on Iterative
Qing-Ping Meng · Science Technology and Engineering · 2012
According to the carrier frequency synchronization in wireless digital communications a carrier frequency offset estimation algorithm is proposed.Discrete Fourier Transform(DFT) interpolation estimated the carrier frequency offset by the iterative algorithm in a wide frequency offset range,and in the estimation accuracy relative to the DFT method has been greatly improved.This algorithm does not increase the DFT data length for Burst work.Finally,a Monte Carlo simulation experiment,and simulation results show that the new algorithm not only has a wide range of estimates,but also has a high estimation accuracy.
