rc2ac() - Signal Processing

r = rc2ac(k,r0) finds
the autocorrelation coefficients, r, of the output
of the discrete-time prediction error filter from the lattice-form
reflection coefficients k and initial zero-lag
autocorrelation r0.

Syntax

r = rc2ac(k,r0)

Example

Compute Autocorrelation SequenceOpen This Example
Determine the autocorrelation sequence that corresponds to a given vector, k, of reflection coefficients and an initial zero-lag autocorrelation given by r0.
k = [0.3090 0.9800 0.0031 0.0082 -0.0082];
r0 = 0.1;
a = rc2ac(k,r0)

a =

    0.1000
   -0.0309
   -0.0791
    0.0787
    0.0294
   -0.0950
