This web site is an interface to a program that allows you compute code parameters for "small" linear Binary Algebraic codes and their various extensions. There is a computational time limit in effect for practical reasons, but if you are interested in coding parameters for a bigger code please feel free to send me e-mail.

Most of the algorithms used for this computation are described in the following documents:

- A. Trachtenberg,
*Designing Lexicographic Codes with a Given Trellis Complexity*, IEEE Trans. Inf. Theory, to appear (expected 1/02): available in ps (1.1M), pdf (343k), or html. - A. Trachtenberg,
*Error-Correcting Codes on Graphs: Lexicodes, Trellises, and Factor Graphs*, my Ph.D. thesis from the University of Illinois at Urbana/Champaign, Department of Computer Science: available in html, postscript (1.2M) or pdf (1M).
