A Unified View of Synchronous Data Transmission System Design

This paper illustrates the basic equivalence of many of the linear data transmission design techniques. It shows the unifying feature of these techniques to be a generalization of Nyquist's original ideas relating time samples and frequency domain constraints. It examines pulse amplitude (with and without constraints on the input data) and pulse shape modulation systems, and shows their relationships. It uses a number of previously-described systems to illustrate the range of possibilities of the very general design approach. This paper presents some new results on noise and channel parameter monitoring and on spectrum shifting by constraining the input data.
