Abstract
Disclosed are a method and an apparatus for estimating a frequency offset in a wireless communication system. The method for estimating a frequency offset of the present disclosure comprises the steps of: acquiring a first symbol from which a cyclic prefix (CP) symbol of a received symbol is removed; acquiring a second symbol from which data having a length corresponding to a length of CP is removed at an end opposite to the end in which the CP is present in the received symbol; and estimating the frequency offset by using the first symbol and the second symbol.
Claims15
A method for estimating a frequency offset of a base station, comprising:
- obtaining a first symbol from which a cyclic prefix (CP) symbol of a received symbol is removed;
- obtaining a second symbol from which data having a length corresponding to the CP symbol is removed at an end opposite to an end in which the CP symbol of the received symbol;
- and
- estimating the frequency offset based on the first symbol and the second symbol.
A base station, comprising:
- a transceiver configured to transmit/receive a symbol;
- and
- a controller configured to estimate a frequency offset using a first symbol from which a cyclic prefix (CP) symbol of the received symbol received through the transceiver is removed, and a second symbol from which data having a length corresponding to the CP of the received symbol is removed at an end opposite to an end in which the CP of the received symbol.
A modem apparatus of a base station, comprising:
- a symbol obtainer configured to:
- obtain a first symbol from which a cyclic prefix (CP) symbol of a received symbol is removed, and
- obtain a second symbol from which data having a length corresponding to the CP is removed at an end opposite to an end in which the CP of the received symbol;
- and
- a frequency offset estimator configured to estimate the frequency offset based on the first symbol and the second symbol.
