Joint decoding and phase estimation: an exercise in factor graphs
Justin Dauwels, Hans‐Andrea Loeliger · 2003
As outlined already by Wiberg [4], iterative algorithms for joint decoding and channel estimation may be derived from the factor graph [2] of the code and the channel. We report some first results from a systematic study of message passing algorithms for joint decoding and phase estimation. We consider discrete-time channels of the form
