STATISTICAL DELTA MODULATION.

Abstract

The report describes the results of a study of Statistical Delta Modulation (SDM) a new mthod of digital transmission of analog information. In this method the system design is tailored to the statistical properties of the input data so as to provide analog reconstruction values with a minimum mean squared error. The method of system design is an iterative procedure in which conditional means are evaluated based upon actual input data. The report presents the theory of operation of the system and describes the results of a computer simulation in which such questions as the effects of sampling rate, channel noise, system memory, and mismatched input processes are discussed. Due to time limitations only a brief comparison was made with conventional techniques. It was found that at low sampling rates and for a second order Gaussian Markoff process, sampling rate reductions of 38% could be achieved relative to a conventional delta modulation system at the same SNR performance.
