dc.description.abstractA method of encryption and transmission of analog signals is presented in which Pulse- Amplitude-Modulation, Frequency Modulation (PAM-FM) techniques are used. This method has the potential for increased capacity over bandwidth constrained channels with no loss of privacy when compared to the current practice of Pulse-Code-Modulation, Phase-Shift-Keying (PCM-PSK). The techniques are described, and quantitative comparative analyses are given. A fading channel scenario is developed in which the capacity of PAM-FM with analog encryption is shown to be twice that of PCM-PSK.
