[GAP Forum] Piping data to a decoder in GAP

[Jaco Versfeld]

Good day,

I have a strange request - I am running bit error rate simulations in Matlab, but would like to compare my results to the list decoder of Sudan (implemented in the Guava package).  Would it be possible to format my data from Matlab, and "pipe" it to GAP, on a per codeword basis?

Also, I am actually interested in soft-decision decoding of RS codes, therefor I will be using modified multiplicity matrices, as per Koetter and Vardy's paper.  Would it be possible to feed the list decoder with a modified multiplicity matrix?

Kind Regards,
Jaco
