Convert autocorrelation sequence to reflection coefficients
[k,r0] = ac2rc(r)
[k,r0] = ac2rc(r) finds
the reflection coefficients,
k, corresponding to
the autocorrelation sequence
the zero-lag autocorrelation. If
r is a matrix
where the columns are separate channels of autocorrelation sequences,
the zero-lag autocorrelation coefficient for each channel. These reflection
coefficients can be used to specify the lattice prediction filter
that produces a sequence with approximately the same autocorrelation
sequence as the given sequence
You can apply this function to real or complex data.
