A table of upper bounds for binary codes

E Agrell, A Vardy, K Zeger - IEEE Transactions on Information …, 2001 - ieeexplore.ieee.org
Let A (n, d) denote the maximum possible number of codewords in an (n, d) binary code. We
establish four new bounds on A (n, d), namely, A (21, 4)/spl les/43689, A (22, 4)/spl …

SA Savari, A Naheta - International Symposium onInformation …, 2004 - ieeexplore.ieee.org
This paper generalizes one-to-one encodings of a discrete random variable to finite code
alphabets with memoryless letter costs and establish some upper and lower bounds on the …

[HTML][HTML] Bounds for binary constant weight codes

AE Brouwer, T Etzion - IEEE Trans. Inf. Theory, 1990 - win.tue.nl
A (n, d, w) is the maximum size of a binary code with word length n, minimum distance d,
and constant weight w. The tables below give the best known lower (and upper) bounds for …

On unique decodability, McMillan's theorem and the expected length of codes

M Dalai, R Leonardi - Technical Report RT 200801-58, Department of …, 2008 - iris.unibs.it
In this paper we propose a revisitation of the topic of unique decodability and of some of the
related fundamental theorems. It is widely believed that, for any discrete source X, every …

Some upper bounds on the redundancy of optimal binary fix-free codes

Tight lower bounds for optimum code length (Corresp.)

J Rissanen - IEEE transactions on information theory, 1982 - ieeexplore.ieee.org
A new lower bound for the mean code length of all one-to-one codes for a random variable
