The wire-tap channel

- A. Wyner
- Computer Science
- The Bell System Technical Journal
- 1 October 1975

We consider the situation in which digital data is to be reliably transmitted over a discrete, memoryless channel (dmc) that is subjected to a wire-tap at the receiver. We assume that the wire-tapper… Expand

The rate-distortion function for source coding with side information at the decoder

Let \{(X_{k}, Y_{k}) \}^{ \infty}_{k=1} be a sequence of independent drawings of a pair of dependent random variables X, Y . Let us say that X takes values in the finite set \cal X . It is desired to… Expand

Coding Theorems for a Discrete Source With a Fidelity CriterionInstitute of Radio Engineers, International Convention Record, vol. 7, 1959.

Consider a discrete source producing a sequence of message letters from a finite alphabet. A single-letter distortion measure is given by a non-negative matrix (d ij ). The entryd ij measures the… Expand

We obtain Shannon-theoretic limits for a very simple cellular multiple-access system. In our model the received signal at a given cell site is the sum of the signals transmitted from within that cell… Expand

The common information of two dependent random variables

- A. Wyner
- Mathematics, Computer Science
- IEEE Trans. Inf. Theory
- 1 March 1975

The problem of finding a meaningful measure of the "common information" or "common randomness' of two discrete dependent random variables X,Y is studied. The quantity C(X; Y) is defined as the… Expand

Information theoretic considerations for cellular mobile radio

- L. H. Ozarow, S. Shamai, A. Wyner
- Computer Science
- 1 May 1994

We present some information-theoretic considerations used to determine upper bounds on the information rates that can be reliably transmitted over a two-ray propagation path mobile radio channel… Expand

Channels with Side Information at the Transmitter

In certain communication systems where information is to be transmitted from one point to another, additional side information is available at the transmitting point. This side information relates to… Expand

On source coding with side information at the decoder

- A. Wyner
- Mathematics, Computer Science
- IEEE Trans. Inf. Theory
- 1 May 1975

Let \{(X_k, Y_k, V_k)\}_{k=1}^{\infty} be a sequence of independent copies of the triple (X,Y,V) of discrete random variables. We consider the following source coding problem with a side information… Expand

Recent results in the Shannon theory

- A. Wyner
- Computer Science
- IEEE Trans. Inf. Theory
- 1974

The first part of this paper consists of short summaries of recent work in five rather traditional areas of the Shannon theory, namely: 1) source and channel coding theorems for new situations; 2)… Expand

Some asymptotic properties of the entropy of a stationary ergodic data source with applications to data compression

Theorems concerning the entropy of a stationary ergodic information source are derived and used to obtain insight into the workings of certain data-compression coding schemes, in particular the… Expand
