Modeling, analysis, and compensation of quantization effects in M-band subband codecs
Richard A. Haddad, Necdet Uzun · IEEE International Conference on Acoustics Speech and Signal Processing · 1993
The authors present a rigorous modeling and analysis of quantization effects in PDF-optimized quantizers for the M-band case. They develop a technique for nulling out the signal distortion and for minimizing quantization noise in the reconstructed output, while imposing perfect reconstruction constraints. The present analysis and compensation are important in situations requiring low average bit per channel allocation.>
