چکیده

In this correspondence we investigate the performance of the Lempel–Ziv incremental parsing scheme on nonstationary sources. We show that it achieves the best rate achievable by a finite-state block coder for the nonstationary source. We also show a similar result for a lossy coding scheme given by Yang and Kieffer which uses a Lempel–Ziv scheme to perform lossy coding.

Efficient universal noiseless source codes

Although the existence of universal noiseless variable-rate codes for the class of discrete stationary ergodic sources has previously been established, very few practical universal encoding methods are available. Efficient implementable universal source coding techniques are discussed in this paper. Results are presented on source codes for which a small value of the maximum redundancy is achie...

Adaptive Vector Quantization for the Coding of Nonstationary Sources

Vector quantization (VQ) has long been a popular technique for data compression due in part to results from rate-distortion theory that show that VQ is asymptotically optimal for the coding of a stationary source. This optimality has inspired a number of algorithms, collectively known as adaptive vector quantization (AVQ), which apply heuristically motivated modi cations to VQ to achieve coding...

Universal noiseless coding

A&ruct-Universal coding is any asymptotically opt imum method of block-to-block memoryless source coding for sources with unknown parameters. This paper considers noiseless coding for such sources, primarily in terms of variable-length coding, with performance measured as a function of the coding redundancy relative to the per-letter conditional source entropy given the unknown parameter. It is...

Universal Coding for Correlated Sources with Memory

|Universal coding problem for the system of Slepian and Wolf (the SW-system) has rst been investigated by Csisz ar and Korner. They considered the correlated memoryless sources, and established a universally attainable error exponent as a function of rate pair (R1;R2) that is positive whenever (R1; R2) is an inner point of the admissible rate region of the SW-system, which is speci ed dependin...

Universal coding for correlated sources over generalized complementary delivery networks

This paper deals with a universal coding problem for a certain kind of multiterminal source coding network called a generalized complementary delivery network. In this network, messages from multiple correlated sources are jointly encoded, and each decoder has access to some of the messages to enable it to reproduce the other messages. Both fixed-to-fixed length and fixed-to-variable length los...
