Abstract:
1. A system for transmitting a quadrature amplitude modulation (QAM) waveform to a receiver, the system comprising: first, second, and third mixers that combine synchronized first, second, and third phase-shift keying (PSK) signals with a common local oscillator signal to form respective first, second, and third amplifiable signals; a first amplifier that receives the first amplifiable signal and powers a first radiator in response to the received first amplifiable signal; second and third amplifiers that receive the second amplifiable signal and power respective second and third radiators in response to the received second amplifiable signal; and fourth, fifth, sixth, and seventh amplifiers that receive the third amplifiable signal and power respective fourth, fifth, sixth, and seventh radiators in response to the received third amplifiable signal; wherein each of the first, second, third, fourth, fifth, sixth, and seventh radiators radiates in one of a plurality of discrete, specified states; and wherein the radiated states from the first, second, third, fourth, fifth, sixth, and seventh radiators combine through far-field electromagnetic propagation and effectively sum at the receiver to mimic transmission from a single amplifier.
