sir,
I am using a voice signal and obtained the subband signals by passing it through a 8 channel QMF filter bank I require the acs values of the sub band signals When computed using the matlab command XCORR ,autocorrelation in some bands is zero Can anybody kindly explain me how to evaluate the autocorrelation values upto lag 'k'.Moreover I want to AR/ARMA model the sond signal.How can i do it what should be the order if the matlab commands available are used.
Thanking you,
