Re: FIR Lattice Filter Reflection Coefficients in Terms of Direct Coefficients? - Spiros Lakkos - 22:00 01-11-04

You can find the relevant information in the following textbooks:

(1) "Advanced Digital Signal Processing",  J.G.Proakis,
C.M.Rader, F.Ling, C.L.Nikias, ISBN 0-02-396841-9,
Chapter 4 (Linear Prediction and Optimum Linear Filters),
pp 219-221

(2) "Optimum Signal Processing, An Introduction, 2nd Edition",
S.J.Orfanidis, ISBN 0-07-100834-9, Chapter 5 (Linear Prediction),
Section 5.7 (Analysis and Synthesis Lattice Filters), p.225-...

(3) "Adaptive Filter Theory, 2nd Edition", S.Haykin,
ISBN 0-13-013236-5, Chapter 6 (Linear Prediction),
Section 6.3 (Levinson-Durbin Algorithm), pp. 198-205

If you are looking for a computer program to perform this task
you can check the FORTRAN and C code given in Orfanidis' book (2).

Hi Spiros,

Thanks very much for the references. I've got the Haykin book at
work - I can check it out without going to the library.
