This study is undertaken to determine whether recent technological progress has resulted in the development of modulation techniques which are superior to frequency modulation for use with mobile or man packed military radio sets. A simplified model of the single channel commun1cation system is developed. In this model the modulation process is considered in two steps. First, some form of speech processing is assumed to be performed. Various types of speech processing considered are clipping, amplitude limiting, filtering, sampling, coding, and vocoding. The second stage of modulation is consi...
