  • Abstract
    We present a new algorithm for fixed-rate vector quantizer (VQ) design with deterministic data net. The algorithm also performs efficient VQ design for simply characterized continuous distributions. The algorithm also serves as an approximation algorithm for the d-dimensional fixed-rate operational distortion-rate function, extends to a variety of network VQ problems. The algorithm generalizes to give ε-approximation algorithms for many network VQ design problems. A few examples are multiresolution VQ (MRVQ), multiple description VQ (MDVQ), side information VQ (SIVQ), Broadcast VQ (BCVQ), joint source-channel VQ (JSCVQ) and remote source VQ (RSVQ).
