ARMA2D
主程序arma2Ddemo是对模拟图像的2DAR和ARMA参数估计。(arma2Ddemo: See and run the demo arma2Ddemo for an example of 2D AR and ARMA parameters estimation from simulated images.
- sim_ar2d: generation of simulated 2D AR process.
- sim_arma2d: generation of simulated 2D ARMA process.
- ar2d: solves 2D yule walker to estimate AR parameters
- arma2d: estimation of 2D ARMA parameters. First step: estimation of the gaussian input by inv_ar2d, Second step: linear system solution to estimates simultaneously AR and MA parameters, as explained in [1].
- inv_ar2d: first step in arma2d. Filters through inverse filter 1/AR an AR process, to generate its innovation Gaussian signal. It is used here to estimate the Gaussian noise input to the ARMA 2D process, approximating the ARMA model to a high order AR model.
- poles2coeff: converts poles chosen by user to AR or MA coefficients (support function)

Windowing
In this letter, we propose anovel family of windowing
technique to compute mel frequency cepstral coefficient (MFCC)
for automatic speaker recognition from speech. The proposed
method is based on fundamental property of discrete time Fourier
transform (DTFT) related to differentiation in frequency domain.
Classical windowing scheme such as Hamming window
