How to prove Line Spectral Pair coefficient properties?

We take the polynomial $a(x)$ of degree $M$ from the denominator of the LPC system function, and represent it as a sum of a palindromic and an anti-palindromic polynomial: $a(x) = 0.5(p(x) + q(x))$, …

What Is the Definition of Linear Predictive Coefficients When the Optimal Value Aren't Unique?

Linear predictive coefficients of signal y are defined as the best $k$ coefficients $a_i, i = 1, \ldots, k$, that will approximate $y_n$ by $-\sum_{i=1}^k{a_iy_{n-i}}$. (Best approximation is that whi …
