Is it possible to find the error location polynomial in t cycles for Reed–Solomon Code using a modified RiBM algorithm?
Recently I've read a paper on Reed–Solomon Code, in the decoding part, the author proposed a modified RiBM algorithm which use t cycles(while RiBM algorithm needs 2t cycles) to find the error location ...

Decoding $\text{RS}(n, k)$ using Reformulated inversionless Berlekamp-Massey algorithm with only $t$ iterations in KES step?
I'm working on RS Enc&Dec, for decoder, I use Reformulated inversionless Berlekamp-Massey (RiBM) algorithm to obtain $\Lambda$ and $\Omega$. However, the original RiBM needs $2t$ iterations (here, ...

How to compute generator matrix from a parity check matrix?
I have a parity matrix ("H") that is not in canonical form (the identity matrix is not on the right side). I'm trying to programatically calculate the generator matrix ("G") from it. The Wikipedia ...
