Logarithmic Cubic Vector Quantization

C Rohlfing, H Krueger, P Vary - Speech Communication; 10 …, 2012 - ieeexplore.ieee.org
In this paper a novel type of gain-shape vector quantization (GSVQ) is presented, denoted
as Logarithmic Cubic Vector Quantization (LCVQ). LCVQ is based on a decomposition of the …
