The invention discloses a method of estimating carrier frequency offset of subscriber terminal, determine the amount of more signal sources which received by subscriber terminal; merge the signals of the base station corresponding to the amount of the base station; estimate carrier offset according to the merged signal. The invention also discloses a device of estimating carrier frequency offset of subscriber terminal, including: judge module, according to the signal which received by subscriber terminal, used to determine the base station amount of signal resources which received by subscriber terminal, merge module, used to merge the signals of the base station corresponding to the amount of the base station, and output the merged signal to the carrier frequency offset obtain module; carrier frequency offset obtain module, used to estimate the carrier frequency offset of the merged signal. According to the invention, the carrier frequency offset of the subscriber terminal will meet the need, and improve the success probability. |
