Iterative algorithm for design of vector quantisation codebooks in nonorthogonal domains
Wasfy B. Mikhael, Venkatesh Krishnan · Electronics Letters · 2002
An iterative algorithm for codebook accuracy enhancement, applicable to both waveform and linear prediction (LP) model-based vector quantisation in nonorthogonal domains, is developed and presented. Sample results are provided which clearly demonstrate the improved performance for the same bit rate.
