<p>Embodiments of the present invention provide a method for processing a signal, which comprises: performing Fourier transform on data in a valid data segment of the signal to be processed, wherein the signal consists of 2K data segments including the valid data segment, valid data of the signal is within the valid data segment, the valid data refers to data whose data is greater than a preset threshold in the signal, and K is an integer greater than 0; and performing interpolation filtering processing on the data after Fourier transform, wherein the Fourier transform comprises either of fast Fourier transform (FFT) and inverse fast Fourier transform (IFFT). Accordingly, the embodiments of the present invention also provide an apparatus for processing the signal. The embodiments of the present invention can reduce an operation overhead of the FFT and the IFFT.</p> |
