Adaptive Redundancy Removal in Data Transmission
Robert W. Lucky · Bell System Technical Journal · 1968
This paper suggests an adaptive filter, similar to that used in automatic equalization, for use as a predictor in data compression systems. It discusses some of the applications of this adaptive predictor in digital data transmission. In the event of redundant data input to the system the predictor could be used to lower the transmitted power output required for a given error rate or to decrease the error rate while maintaining constant transmitted power. The action of these redundancy-removal and restoration systems is analyzed in simple cases involving Markov inputs.
