Abstract
A method for frequency performing offset estimation and channel estimation includes performing frequency offset estimation on the received data, and obtaining a frequency offset estimation result when interference signals in received data are not obtained, After the interference signals in the received data are obtained, the method includes performing frequency offset estimation on the received data according to the interference signals, and obtaining a frequency offset estimation result. Channel estimation is performed on the received data according to the frequency offset estimation result, and a channel estimation result is obtained. Interference signals are obtained according to the frequency offset estimation result and the channel estimation result, where the interference signals are used as parameters of the frequency offset estimation.
