Speech compression using Linear Predictive Coding

NettetLinear predictive coding The main feature of the quantizers shown in Figs 5.1, 5.2 is that they exploit not all advantages of predictive coding. •Prediction coefficients used in these schemes are not optimal •Prediction is based on past reconstructed samples and not true samples •Usually coefficients of prediction are chosen by using some NettetLinear Prediction. The system in Figure 1 is a linear system. We use least squares which solves linear equations. Actually, the system is using linear prediction where in … eurail london to edinburgh
