ABSTRACT:
The oscillator at the sending node of a wireless digital network, generates a carrier signal, starting at a first instant. A modulator coupled to the oscillator performs phase shift modulating of the carrier signal with an input signal. A spoiler signal generator is coupled to the modulator, for providing a spoiler signal as the input signal, starting at the first instant and continuing for a first duration which is longer than a period needed for the oscillator to achieve stable characteristics. A transmitter is coupled to the modulator at the sending node, for transmitting a wireless radio signal representation of the carrier signal phase shift modulated with the spoiler signal to a receiver at a receiving node. The spoiler signal in the modulated carrier signal interrupts the periodic characteristic of the pulses, and thereby prevents the carrier sensor from detecting the carrier signal. Further, the spoiler signal ceases to modulate the carrier signal after the first duration when the oscillator has achieved stable characteristics, thereby enabling the carrier sensor to detect the carrier signal.
