galois.BCH.k

property galois.BCH.k : int

The message size $k$ of the $[n, k, d]_{q}$ code. This is also called the code dimension.

Examples

Construct a binary $BCH (15, 7)$ code.

In [1]: bch = galois.BCH(15, 7); bch
Out[1]: <BCH Code: [15, 7, 5] over GF(2)>

In [2]: bch.k
Out[2]: 7

Construct a $BCH (26, 14)$ code over $GF (3)$ .

In [3]: bch = galois.BCH(26, 14, field=galois.GF(3)); bch
Out[3]: <BCH Code: [26, 14, 7] over GF(3)>

In [4]: bch.k
Out[4]: 14
