Re: Vector Quantization: Problem with designing codebook

To my knowledge, the best results for the LPC quantization are somewhere around 20 bits per vector. 


This is just a guess:

By 20 bits per 10-dimensional vector do you mean that you assign 2 bits per
coefficient in the 10-dimensional vector?


No.

It is the vector quantization of 10-dimensional LSF vector using the total of 20 bits for indexing the codebooks.
