ac2rc - Convert autocorrelation sequence to reflection coefficients
Syntax
[k,r0] = ac2rc(r)
Description
[k,r0] = ac2rc(r) finds
the reflection coefficients k corresponding to
the autocorrelation sequence r. r0 contains
the zero-lag autocorrelation. If r is a matrix
where the columns are separate channels of autocorrelation sequences, r0 contains
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 r.
Remarks
You can apply this function to real or complex data.
