Performance Comparison between Hermitian codes and Shortened Non-binary BCH codes

COMCAS (2009)

Abstract

We explore the benefits of implementing Hermitian codes over moderate lengths and compare the hard decision decoding performance in the additive white Gaussian noise (AWGN) channel and performance in the erasure channel of Hermitian codes with shortened non-binary Bose Hocquenghem Chaudhuri (BCH) codes. We implement the Berlekamp-Massey- Sakata (BMSA) decoding and Berlekamp-Massey (BMA) decod- ing for the hard decision Hermitian and BCH codes respectively, maximum likelihood erasure decoding and ordered reliability soft decision decoding for both.
