Frequency-shifted feedback cavity used as a phased array antenna controller and carrier interference multiple access spread-spectrum transmitter

A multicarrier-signal generator including:

• a pulse generator capable of generating a plurality of periodic pulses, the periodic pulse having at least one pulse period and a frequency spectrum comprising a plurality of carrier signals having equally spaced frequencies with a frequency spacing that is a function of the at least one pulse period,
• a modulator coupled to the pulse generator, the modulator adapted to modulate at least one information signal onto at least one of the periodic pulses, and
• a frequency selector coupled to at least one of the modulator and the pulse generator, the frequency selector capable of selecting the plurality of carrier signals to be within at least one predetermined frequency band.

A method of generating a multicarrier signal including:

• providing for generating a plurality of information-modulated periodic pulses including generating a plurality of carrier signals having equally spaced carrier frequencies, summing the carrier signals to generate periodic pulses having at least one pulse period, and modulating information onto the periodic pulses, the information-modulated periodic pulses having at least one of a set of signal characteristics that is a function of at least one information signal, the set of signal characteristics including amplitude, phase, time, and frequency, and
• providing for selecting the plurality of carrier signals to be within at least one predetermined frequency band.
