该方法频率偏移量计算简单且采用递推dft，有效减少了计算量。
This method is easy to compute the frequency offset and adopts the recursive DFT method.
频率估计装置57、定时估计装置58分别将频率偏移量和定时偏移量通过控制信道从移动台接收的信号中检测出来。
Frequency and timing estimating units (57, 58) measure frequency and timing offsets, respectively, from a signal received from a mobile station via a control channel.
它可以通过改变信号的类型、频率、幅值、偏移量等参数值求取对应的周期信号和随机信号的幅值特征值。
Through changing some parameters such as type, frequency, amplitude, offset, and so on, it can get the amplitude eigenvalue that corresponding with the cycle signal and the stochastic signal.
