CASA Function: CyclicEncode

Encode using matrix multiplication.

Calling Sequence:

• c := CyclicEncode(a, C)

Parameters:

a : list, vector

• The message to encode.

C : casa/finite/Cyclic/BCH2

• The code used for encoding

Result:

c : vector

• The coded message. c = a * G, where G is the generator matrix of the code C.

Description:

• Encodes a message using the 2 dimensional cyclic code C. Encoding is done by a simple matrix multiplication.

Examples:

> F4:= finiteField(4);

> C:=BCH2(3, 3, [4,0], F4);

> CyclicEncode([seq(1, i=1..C["k"])], C);
