Creation of unequal error protection codes for two groups of symbols

Eugeniusz Kuriata (2008)

International Journal of Applied Mathematics and Computer Science

Similarity:

This article presents problems of unequal information importance. The paper discusses constructive methods of code generation, and a constructive method of generating asymptotic UEP codes is built. An analog model of Hamming's upper bound and Hilbert's lower bound for asymptotic UEP codes is determined.

Divisible Codes - A Survey

Ward, Harold (2001)

Serdica Mathematical Journal

Similarity:

This paper surveys parts of the study of divisibility properties of codes. The survey begins with the motivating background involving polynomials over finite fields. Then it presents recent results on bounds and applications to optimal codes.

Codes that attain minimum distance in every possible direction

Open Mathematics

Similarity:

The following problem motivated by investigation of databases is studied. Let 𝒞 be a q-ary code of length n with the properties that 𝒞 has minimum distance at least n − k + 1, and for any set of k − 1 coordinates there exist two codewords that agree exactly there. Let f(q, k)be the maximum n for which such a code exists. f(q, k)is bounded by linear functions of k and q, and the exact values for special k and qare determined.
