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,"3551")

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.

BCH::BCH ( int in_n,

int in_k,

int in_t,

ivec genpolynom

)

Initialize a (n,k)-code that can correct t errors.

bvec BCH::decode ( const bvec & codedbits )

Decode a bvec of coded data.

bvec BCH::encode ( const bvec & uncodedbits )

Encode a bvec of indata.

double SPUC::BCH::get_rate ( ) [inline]

Get the code rate.
