INVESTIGATION OF ANALOG AND DIGITAL COMMUNICATION SYSTEMS (PHASE 3 REPORT)

Abstract

The results of fundamental investigations on a variety of topics related to the optimization of analog and digital data communication systems are presented. The maximum likelihood estimation of FM-modulated signals is investigated. A study is made of theshold phenomenon in FM reception with an ideal discriminator and a postdetection Wiener filter for the case of a random modulation function. Information theory is applied to establish bounds on the performance of analog communications systems. The performance of PCM systems for transmitting analog information is investigated and compared with theoretical bounds for systems of prescribed complexity. Previous work on the partial ordering of digital channels by the criterion of inclusion was extended. The analysis of the optimization of N-ary digital systems operating over a dispersive channel, which was begun during a previous phase of the contract, is further advanced.
