Frequency offset estimation based on virtual carrier in OFDM system
Sensitivity to carrier frequency offset (CFO) is one of the main drawbacks in OFDM system. This paper focuses on the CFO estimation algorithm based on virtual carrier (VC), and proposes a method on how to choose VCs reasonably in order to both estimate the CFO correctly and reduce the amount of calculation. Simulation results based on Matlab have verified the validation.
