WebThe Berlekamp–Welch algorithm, also known as the Welch–Berlekamp algorithm, is named for Elwyn R. Berlekamp and Lloyd R. Welch. The algorithm efficiently corrects errors in BCH codes and Reed–Solomon codes (which are a subset of BCH codes). Unlike many other decoding algorithms, and in correspondence with the code-domain … WebJul 14, 2011 · An efficient algorithm which synthesizes all shortest linear-feedback shift registers generating K given sequences with possibly different lengths over a field is derived, and its correctness is proved. The proposed algorithm generalizes the Berlekamp-Massey and Feng-Tzeng algorithms and is based on Massey’s ideas.
