Detailed Description

Class for binary, narrow-sense BCH codes.

The notation used is found in S. B. Wicker, "Error control systems for digital communication and storage", Appendix E, Prentice-Hall, 1995.

Example:

 BCH bch(31,21,2,"3 5 5 1")

uses the generator polynomial $g(x) = x^{10} + x^9 + x^8 + x^6 + x^5 + x^3 + 1$ , and is capable of correcting 2 errors with n = 31 and k = 21.
