A Low Complexity Algorithm and Architecture for Systematic Encoding of Hermitian Codes
Rachit Agarwal, Ralf Koetter, Emanuel Popovici
We present an algorithm for systematic encoding of Hermitian codes. For a Hermitian code defined over GF(q^2), the proposed algorithm achieves a run time complexity of O(q^2) and i…
