20100 A new structure for Cyclic codes David Lucas "This ticket proposes a new implementation for cyclic codes.
It contains:
- a new code class, `CyclicCode`,
- a dedicated encoder to compute the generator matrix of a Cyclic Code, and
- an encoder whose message space is a polynomial ring.
This new structure has the following features:
- it is now possible to build a cyclic code in three different ways:
- either by using the generator polynomial, which is passed as an argument,
- either by using the defining set, which is passed as an argument (and can even be partial), or
- by passing a linear code as argument. In that case, a generator polynomial will be computed (if possible) and used to reformat the input code as a cyclic code.
- it also comes with a method to compute the BCH bound, either from a constructed code or directly from the necessary parameters.
