MFCC circular power spectral model

We now construct an ``MFCC-like" data model. The structure of MFCC is defined in the frequency-domain by the MEL band functions. Let $ (N/2+1)\times K$ matrix $ {\bf A}$ contain the spectral band functions. We define the circular power spectrum of an MFCC-like process as

$\displaystyle \mbox{\boldmath$\rho$}$$\displaystyle _w = {\bf A} {\bf b},$ (10.5)

where $ {\bf b}$ is a $ K\times 1$ vector of positive values.
