Noiseless coding of correlated information sources
  • D. Slepian, J. Wolf
  • Mathematics, Computer Science
  • IEEE Trans. Inf. Theory
  • 1 September 1973
TLDR
We determine the minimum number of bits per character R_X and R_Y needed to encode these sequences so that they can be faithfully reproduced under a variety of assumptions regarding the encoders and decoders. Expand

Efficient maximum likelihood decoding of linear block codes using a trellis
  • J. Wolf
  • Computer Science
  • IEEE Trans. Inf. Theory
  • 1978
TLDR
It is shown that soft decision maximum likelihood decoding of any (n,k) linear block code over GF(q) can be accomplished using the Viterbi algorithm applied to a trellis with no more than q^{(n-k)} states. Expand

Windowed Decoding of Protograph-Based LDPC Convolutional Codes Over Erasure Channels
TLDR
We show that the structure of LDPC convolutional code ensembles is suitable to obtain performance close to the theoretical limits over the memoryless erasure channel, both for the BP decoder and windowed decoding. Expand

A pragmatic approach to trellis-coded modulation
TLDR
We have shown that with a very simple signal mapping, it is possible to utilize existing good binary convolutional encoderdecoders to implement trellis-coded modulators with performance gains (in required energy-to-noise ratios) greater than 3 dB and in some cases approaching 6 dB, for moderately to highly bandlimited channels.

Transmission of noisy information to a noisy receiver with minimum distortion
  • J. Wolf, J. Ziv
  • Computer Science
  • IEEE Trans. Inf. Theory
  • 1 July 1970
TLDR
This paper is concerned with the transmission of information with a fidelity criterion where the source output may be distorted prior to encoding and, furthermore, where the output of the decoder may be distortion prior to delivery to the final destination. Expand

The capacity region of a multiple-access discrete memoryless channel can increase with feedback (Corresp.)
TLDR
The capacity of a single-input single-output discrete memoryless channel is not increased by the use of a noiseless feedback link. Expand

Codes for Digital Recorders
TLDR
This paper surveys the theory and practice of constrained coding, tracing the evolution of the subject from its origins in Shannon's classic 1948 paper to present-day applications in high-density digital recorders. Expand

Permutation codes for sources
Source encoding techniques based on permutation codes are investigated. For a broad class of distortion measures it is shown that optimum encoding of a source permutation code is easy to instrumentExpand
