Title:

Dear
Members of the list:

My
question is related to quantization of Linear Prediction (LP)
Parameters.

I know
very well that LP parameters are mapped onto Reflection Coefficients and we get
a lattice filter.

Now,
lets say I have an order K Lattice filter: implying that I’ve a concatenation of
first-order lattice filters.

If we
quantize the parameters (i.e. the reflection coefficients) of each these
first-order sections we get a Spectral Distortion associated with it, say D_k (k
= 1,2,….,K). I would like to know if there is any straightforward relationship
between these first-order Spectral Distortions to the overall Spectral
Distortion in an order-K system.

For
example, lets say, D_total = D_1 + D_2 +…… + D_K.

Is
there any work done on this field? Is it possible to predict the overall
distortion just from the knowledge of the distortion in the first-order section?

I’ll
be extremely grateful if someone can cite some references or maybe some
indication on the overall distortion.

Best
Regards,
