    Abstract: A pipeline decoding system for performing pipelined decoding of a codeword characterized by one or more parity checks may include a first pipeline stage circuit configured to process a first parity set composed of one or more first parity checks of the codeword and to process a second parity set composed of one or more second parity checks of the codeword, a second pipeline stage circuit configured to generate one or more codeword update messages for the second parity set based on a first estimate of the codeword, and a third pipeline stage circuit configured to update the first estimate of the codeword with one or more codeword update messages for the first parity set to obtain a second estimate of the codeword.
