An object of the patent is to provide a system for transmitting a signal from a transmitter station to a receiver station without any decrease in the discernibility of the signal due to jamming techniques which may be effected. A further object is to increase the strength of a signal at a receiver station when a carrier wave carrying the signal has been jammed on its carrier frequency. Still another object is to provide a system for effectively commanding a missile in its trajectory, even though a carrier wave carrying a command signal has been jammed by an enemy station. Yet another object is to eliminate the need of a local oscillator and an automatic frequency control circuit in a receiver at a receiving station. A still further object is to reduce the weight and increase the efficiency within a receiver station receiving command signals.
