The Best, The Requested, and The Default Non-Binary LDPC Decoding Algorithm

This paper presents a different vision of the Non-Binary LDPC decoding algorithm. So far, state-of-the-art decoders are mainly focused on the reduction of the check node processing complexity, with a potential side effect on the size of the messages that are exchanged in the iterative decoder. However, it is possible to take a different approach and consider the reduction of the message size as th...
