High Accuracy Measure of Carrier Frequency Offset in Flat-Fading Channels

摘要

The algorithm in the paper combines the segmented DFT phase difference method and the second-order cyclic spectral analytical method to high accurately measure the carrier frequency offset of a linearly modulated signal transmitted through a frequency-flat fading channel. It not only compensates the channel, but also advances the measure precision. Simulation results show this algorithm is feasible and is easy to implement.
