Abstract
A method of reconstructing a damaged sequence of symbols where some symbols are missing is provided in which statistical parameters of the sequence are used with confidence windowing techniques to quickly and efficiently reconstruct the damaged sequence to its original form. Confidence windowing techniques are provided that are equivalent to generalized hidden semi-Markov models but which are more easily used to determine the most likely missing symbol at a given point in the damaged sequence being reconstructed. The method can be used to reconstruct communications consisting of speech, music, digital transmission symbols and others having a bounded symbol set which can be described by statistical behaviors in the symbol stream.
