发明名称 IMPROVED METHOD AND MEANS OF DETERMINING COEFFICIENTS FOR LINEAR PREDICTIVE CODING
摘要 An improved method and means of determining reflection coefficients that characterize an electrical signal obtains characteristics of an all-zero inverse lattice filter. The reflection coefficients are obtained by filtering the signal, sampling the filtered signal, obtaining the elements of a correlation matrix from the samples, initializing values of matrices of forward residuals, backward residuals, and cross correlation of residuals, combining matrix elements to obtain a first reflection coefficient, removing from the forward, backward an cross-correlation matrices the effect of the first reflection coefficient, calculating from the revised matrices a second reflection coefficient, and repeating the calculations to the desired order.
