Abstract
A signal processing apparatus () according to the present disclosure includes: an overlap-type FFT processing unit () that performs FFT processing overlapping input subcarrier signals each other for each of FFT blocks, and a generation unit () that generates a signal which is obtained by frequency shifting the subcarrier signals that have been subjected to the FFT processing by the overlap-type FFT processing unit () by a frequency shift amount of a subcarrier, a phase offset that occurs between the FFT blocks overlapping each other being compensated in the signal.
