COMMUNICATION SYSTEMS TECHNIQUE BASED ON FUNDAMENTAL CONCEPTS OF JACQUES HADAMARD

Abstract

A variety of fundamental investigations, with common analytical foundation in the work of Jacques Hadamard, was conducted for the purpose of development of advanced communications systems. Chapter I presents a functional analysis approach to the demodulation problem as formulated in a system of integral equations by D. C. Youla. Its principal content is the discussion of the engineering significance of a quadratic variable principle that underlies the Youla formulation. Chapter II concentrates on mathematical considerations with the dual purpose of completing the arguments involved in Chapter I and indicating where forward work is needed to enlarge the domain of the validity of the theory of Chapter I. Chapter III presents communication techniques derivable from incidence matrices of balanced incomplete block design configurations.
