Chapter 6 Linear Predictive Coding (LPC) of Speech Signals. 6.1 Basic Concepts of LPC 6.2 Auto-Correlated Solution of LPC 6.3 Covariance Solution of LPC 6.4 LPC related parameters and their relationships. 6.1 Basic Concepts of LPC (1). It is a parametric de-convolution algorithm
then V(Z) could be found, and E(Z) could be found also. This finishes de-convolution.
qi(j) = qi-1(j) + ki *qi-1 (i-j)
ki = qi-1(j)/qi(0)
aj(i) = qi-1(i-j)
E(i) = E(i-1)(1-ki2)
Q(z) = A(p)(z)- z-(p+1)A(p)(z-1)
