Paper Abstract
In this paper, a variable rate lattice VQ algorithm for vector subband coding is proposed. It is a modification of a two-stage vector quantization-lattice vector quantization (VQ-LVQ) algorithm introduced by J. Pan and T. R. Fischer. After the modification, the new algorithm is designed to target low-bit rate coding instead of moderate bit rate to high bit rate coding in the original design. The new algorithm has been applied to a low bit rate vector subband coding scheme. Simulation result shows it can reduce the memory requirement while offering even better rate-distortion performance (up to 1 db) than regular unstructured VQ.
