    • 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.
    • 本发明公开了一种估计用户终端载波频偏的方法,确定用户终端接收的信号源数量; 合并基站对应的基站信号; 根据合并的信号估计载波偏移。 本发明还公开了一种估计用户终端载波频偏的装置,包括:判断模块,根据用户终端接收到的信号,用于确定用户终端接收的信号资源的基站量,合并模块,使用 合并与基站量相对应的基站信号,并将合并的信号输出到载频偏移获取模块; 载频偏移获取模块,用于估计合并信号的载波频率偏移。 根据本发明,用户终端的载频偏移将满足需要,提高成功概率。
