A Feasibility Study of a Hybrid Secure Voice Coding Processor.
Abstract
An investigation of a proposed hybrid voice coding system proved the feasibility of such a system to provide a privacy voice channel with an acceptable degree of intelligibility. The proposed system is basically a voice inversion system employing a randomly generated carrier frequency for inversion. The random carrier frequency generator is controlled by a programmable, digital character generator. The hybrid system is readily adaptable to present military and civilian VHF/UHF voice communications systems at a relatively low cost and with a very minimum of equipment modification. (Author)
