Performance Rating for Analogue and Digital Modulation Methods.
Abstract
Equations are derived which relate the required signal power to the output signal-to-noise (S/N) ratio for essentially all existing modulation methods (both digital and analogue). This constitutes a meaningful measure of performance when fidelity of intelligibility identifies the user needs. The results clearly establish that performance, and therefore a preferred or optimum modulation method, is strongly dependent upon the required or desired output S/n ratio. The performance equations and curves may be utilized in conjunction with other ssystem requirements to arrive at a preferred modulation concept based upon some combined performance criterion or they may be employed directly to identify an optimum system based upon a minimum transmitter power requirement.
