Abstract:

The specific question which the study has attempted to answer is -- is it possible to improve the performance of single channel tactical radio communications by utilizing modulation techniques different from those presently employed. The answer is yes, it is possible. The development of a practical vocoder system with bit rates of 6000 bits per second, or less, with reasonable intelligibility, will provide a system which exhibits spectrum utilization at least three times as efficient as FM and is superior to FM as regards signal to noise ratio. The study also shows that such a vocoder system would be a frequency modulated digital system and would possess the advantages of immunity to interference and nuisance jamming to a slightly greater degree than FM. This would minimize the need for operator training. Author
