Signal Processing In Digital Recording: The Delayed Decision Feedback Sequence Estimation Algorithm
Alexandra Duel‐Hallen, Chris Heegard · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1986
Delayed Decision Feedback Sequence Estimation (DDFSE) is a new signal processing algorithm for the detection of signals in the presence of noise. This paper describes the role of DDFSE in digital recording. The potential performance and complexity advantages of this algorithm are demonstrated by comparison to existing, alternative techniques.
