SIGNAL PROCESSING METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/179740

Kind Code:

A1

Abstract:

Embodiments of the present invention provide a signal processing method and apparatus. The method comprises: filtering an input signal in M paths so as to obtain M filter signals; extracting the M filter signals respectively so as to obtain M extracted signals; then, performing fast Fourier transform (FFT) on the M extracted signals respectively so as to obtain M frequency domain signals; and finally, determining, according to the M frequency domain signals, an output signal. By filtering and extracting signals and performing FFT, the embodiments of the present invention can reduce the operation complexity.
