摘要：
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.
