Message-passing decoders and their application to storage systems

Message-passing has been proposed for decoding parity check codes, especially low density parity check (LDPC) codes. We propose using message-passing detectors for partial response channels. Furthermore, we investigate how a single message-passing detector/decoder can be matched to a combination of...

Description
Summary:Message-passing has been proposed for decoding parity check codes, especially low density parity check (LDPC) codes. We propose using message-passing detectors for partial response channels. Furthermore, we investigate how a single message-passing detector/decoder can be matched to a combination of a partial response channel and a LDPC code.
