CASA Function: BCH2
Prepare a 2-dimensional BCH-code.
Calling Sequence:
- C := BCH2(N1, N2, delta, F)
Parameters:
- N1 : integer
- The x value of the domain of C.
- N2 : integer
- The y value of the domain of C.
- delta : list of integer
- The parameter delta of the 2-dim BCH code.
- F : casa/finite/Field
- The field over which C is defined.
Result:
- C : table
- The BCH code of domain (N1,N2) with parameter delta over the field F
Description:
- Prepares the 2-dimensional BCH-code C.
- The code is a table with the following entries:
- G: The generator matrix.
- GIn: The generator matrix, in RootOf form.
- H: The parity check matrix.
- HIn: The parity check matrix, in RootOf form.
- infopos: The set of info-positions.
- Roots: The common roots of G.
- n: The length of the code
- k: The dimension of the code
Examples:
> C1 := BCH2(3,3,[1,0], finiteField(4));
