Extension of the Fixed-Rate Structured Vector quantizer to Vector Sources
(1991)
The fixed-rate structured vector quantizer (SVQ) derived from a variable-length scalar quantizer was originally proposed for quantizing stationary memoryless sources. In this paper, the SVQ has been extended to a specific ...
On Optimal Shaping of Multidimensional Constellations - An Alternative Approach to Lattice-Bounded (Voronoi) Constellations
(1992)
A scheme for the optimal shaping of multidimensional constellations is proposed. This scheme uses some of the ideas from a type of structured vector quantizer originally proposed for the quantization of memoryless sources, ...
Trellis-Based Scalar-Vector Quantizer for Memoryless Sources
(1992)
This paper describes a structured vector quantization approach for stationary memoryless sources that combines the scalar-vector quantizer (SVQ) ideas (Laroia and Farvardin) with trellis coded quantization (Marcellin and ...
A Structured Fixed-Rate Vector Quantizer Derived from Variable- Length Encoded Scalar Quantizers
(1990)
The well-known error propagation problem inherent in any variable-length coding operation limits the usefulness of variable-length encoded entropy-constrained scalar quantizers when the quantizer outputs are to be transmitted ...
On SVQ Shaping of Multidimensional Constellations - High-Rate Large-Dimensional Constellations
(1992)
An optimal shaping scheme for multidimensional constellations, motivated by some ideas from a fixed-rate structured vector quantizer (SVQ), was recently proposed by Laroia. It was shown that optimal shaping could be performed ...
A Simple and Effective Precoding Scheme for Noise Whitening on Intersymbol Interference Channels
(1992)
A precoding scheme for noise whitening on intersymbol interference channels is presented. This scheme is compatible with trellis-coded modulation and unlike Tomlinson precoding allows constellation shaping. It can be used ...
Design and Analysis of a Fixed-Rate Structured Vector Quantizer Derived from Variable-Length Scalar Quantizers
(1992)
The implementation complexity of the LBG VQ is unaffordable even for quantization at low rates and moderate block-lengths. To overcome the complexity problem, in this thesis we have adopted a structured quantization approach ...
A Structured Fixed-Rate Vector Quantizer Derived from a Variable-Length Scalar Quantizer
(1991)
The well-known error propagation problem inherent in any variable-length coding operation limits the usefulness of variable-length encoded scalar quantizers for transmission over noisy channels. In the absence of channel ...
