Latest Patents
One of his latest patents is titled "Method and apparatus for a data-dependent noise predictive Viterbi." This invention presents an improved Viterbi detector where each branch metric is calculated based on noise statistics that depend on the signal hypothesis corresponding to the branch. The patent also describes a method to reduce the complexity of branch metric calculations by clustering branches that correspond to signals with similar signal-dependent noise statistics. A key feature of this architecture is the clustering of branch metrics into multiple groups, with all members of each group drawing input from a single, shared noise predictive filter. This innovation addresses the issue of physical imperfections in recorded user data, which have become a dominant source of noise in read-back data. The Viterbi detector exploits the statistical dependence of noise on the intended signal, enhancing the reliability of data retrieval.
