#### Detection of Binary Sources Over Discrete Channels with Additive Markov Noise

(1994)

We consider the problem of directly transmitting a binary source with an inherent redundancy over a binary channel with additive stationary ergodic Markov noise. Out objective is to design an optimum receiver which fully ...

#### Optimal Detection of Discrete Markov Sources Over Discrete Memoryless Channels - Applications to Combined Sources-Channel Coding

(1992)

We consider the problem of detecting a discrete Markov source which is transmitted across a discrete memoryless channel. The detection is based upon the maximum a posteriori (MAP) criterion which yields the minimum probability ...

#### Finite-State Vector Quantization for Noisy Channels

(1992)

Under noiseless channel conditions and for sources with memory, finite-state vector quantizers (FSVQs) exhibit improvements over memoryless vector quantizers. It is shown, however, that in the presence of channel noise, ...

#### Entropy-Constrained Trellis Coded Quantization: Implementation and Adaptation

(1993)

Entropy-constrained trellis coded quantization (ECTCQ) of memoryless sources is known to be an efficient source coding technique in the rate-distortion sense. We develop an ECTCQ scheme that employs a symmetric reproduction ...

#### Variable-Rate Finite-State Vector Quantization and Applications to Speech and Image Coding

(1991)

A finite-state vector quantizer is a finite-state machine that can be viewed as a collection of memoryless full-searched vector quantizers, where each input vector is encoded using a vector quantizer associated with the ...

#### A Perceptually Motivated Three-Component Image Model

(1992)

In this paper, results of phychovisual studies of the human visual system are discussed and interpreted in a mathematical framework. The formation of the perception is described by appropriate minimization problems and the ...

#### 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 ...

#### 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 ...

#### Joint Design of Block Source Codes and Modulation Signal Sets

(1990)

We consider the problem of designing a bandwidth-efficient, power-limited digital communication system for transmitting information from a source with known statistics over a noisy waveform channel. Each output vector of ...
