Adaptive Multistage Vector Quantization
نویسنده
چکیده
In this paper, we present a new multiple stage vector quantization method that allows the adaptation of the quantizer to signal to be coded. This adaptation is computationally very simple and is made with no increase in bit-rate. The resul t ing quant izer prov ides a robust performance across different speakers and environments. I t has been applied to the quantization of the LPC parameters and the results show a signif icant increase in performance respect to conventional multi-stage vector quantizers.

A New Multistage Lattice Vector Quantization with Adaptive Subband Thresholding for Image Compression
Lattice vector quantization (LVQ) reduces coding complexity and computation due to its regular structure. A new multistage LVQ (MLVQ) using an adaptive subband thresholding technique is presented and applied to image compression. The technique concentrates on reducing the quantization error of the quantized vectors by “blowing out” the residual quantization errors with an LVQ scale factor. The ...
متن کاملA generalized multistage VQ approach for spectral magnitude quantization
This paper presents a novel vector quantization (VQ) technique in which the quantized vector is formed by adding the transformed outputs of a multistage codebook rather than just adding the outputs of the stages as in regular multistage vector quantization (MSVQ). The transformations are selected from a family of linear transformations represented by a codebook of matrices. This technique can b...

Lattice vector quantization (LVQ) reduces computational load and design complexity due to its regular structure. In this letter, we introduce and analyze the performance of two hybrid combinations of two lattices i.e. the AnAn and AnDn. Experiment results show that multistage LVQ with lattice AnA combination in four dimensional vector offers the least quantization errors with p = 0.0098 as comp...

This paper investigates the use of a new hybrid vector quantizer called switched multistage vector quantization (SWMSVQ) technique using hard and soft decision schemes, for coding of narrow band speech signals. This technique is a hybrid of switch vector quantization technique and multistage vector quantization technique. SWMSVQ quantizes the linear predictive coefficients (LPC) in terms of the...
متن کاملRobust jointly optimized multistage vector quantization for speech coding
In this paper, a novel channel–optimized multistage vector quantization (COMSVQ) codec is presented in which the stage codebooks are jointly designed. The proposed codec uses a signal source and channel–dependent distortion measure to encode line spectral frequencies derived from segments of a speech signal. Simulation results are provided to demonstrate the consistent reduction in the spectral...
