I'm trying to construct a cepstrum using MATLAB built in function but I don't get the difference between MATLAB's functions rceps and cceps. Can anyone explain to me the difference between rceps and cceps?
- rceps: The real cepstrum is the inverse Fourier transform of the real logarithm of the magnitude of the Fourier transform of a sequence.
- cceps: Cepstral analysis is a nonlinear signal processing technique that is applied most commonly in speech processing and homomorphic filtering. It returns the complex cepstrum of the real data sequence using the Fourier transform. [Matlb signal processing tool box]
