摘要：
信道特性计算部(23)根据接收信号中包含的SP信号来估计信道特性，码元插值滤波器(24)能够对频率传递特性进行频移，对信道特性计算部(23)的输出信号进行滤波。滤波控制部(27)根据接收信号中包含的CP信号来估计信道特性，观测估计出的信道特性来决定使码元插值滤波器(24)的频率传递特性进行频移的移动量。码元插值滤波器(24)根据滤波控制部(27)决定的移动量对频率传递特性进行频移。
摘要（英）：

A transmission line characteristic calculating section (23) estimates a transmission line characteristic according to an SP signal contained in a received signal. A symbol interpolation filter (24) is capable of frequency-shifting a frequency transfer characteristic and filters an output signal of the transmission line characteristic calculating section (23). A filter control unit (27) estimates the transmission line characteristic according to a CP signal contained in the received signal and observes the estimated transmission line characteristic to determine the amount to frequency-shift the frequency transfer characteristic of the symbol interpolation filter (24). The symbol interpolation filter (24) frequency-shifts the frequency transfer characteristic according to the amount of the shift determined by the filter control unit (27).
