Apparatus and method for frequency offset estimation in mobile communication system |
| 摘要 |
A method and apparatus estimate a frequency offset of a receiver in a mobile communication system. A pilot signal and a signal of a control channel are received from a transmitter. Frequency offsets of the pilot signal and frequency offsets of the control channel are estimated, respectively. And the frequency offset of the pilot signal is corrected based on the frequency offset estimation of the control channel. |

1. A method for estimating a frequency offset of a receiver in a mobile communication system, the method comprising:
receiving, from a transmitter, a pilot signal and a signal of a control channel; estimating a frequency offset of the pilot signal and a frequency offset of the control channel; and correcting the frequency offset of the pilot signal based on the estimated frequency offset of the control channel, wherein correcting the frequency offset of the pilot signal based on the estimated frequency offset of the control channel comprises correcting the frequency offset of the pilot signal to make the frequency offset of the pilot signal more similar to the estimated frequency offset of the control channel. |
