In the proposed speech … Linear prediction (signal estimation) goes back to at least 1940s when Norbert Wiener developed a mathematical theory for calculating the best filters and predictors for detecting signals hidden in noise. Soon after Claude Shannon established a general theory of coding, work on predictive coding was done by C. Chapin Cutler, Bernard M. Oliver and Henry C. Harrison. Peter Elias in 1955 published two papers on predictive coding of signals.
