NettetThe synthesis portion 'LPC Synthesis', which is found in the receiver section of the system, reconstructs the original signal using the reflection coefficients and the residual signal. In this simulation, the speech signal … NettetIn order to understand the algorithm, however, it's useful to have a simple implementation in Matlab. By using Matlab's primitives for FFT calculation, Levinson-Durbin recursion etc., the Matlab code can be made quite small and transparent. Mike Shire started this implementation in 1997 while he was a graduate student in Morgan's group at ICSI.
