Abstract:
An encoder can convert a stream of data into three or four synchronized 4-PSK signals, for 64-QAM and 256-QAM, respectively. Three or four mixers can combine the three or four synchronized PSK signals with a common local oscillator signal to form three or four respective amplifiable signals, which can all have the same amplitude. One amplifier receives a first of the amplifiable signals and powers one radiator. Two amplifiers both receive a second of amplifiable signals and power two respective radiators. Four amplifiers receive a third of the amplifiable signals and power four respective radiators. The amplifiers can all operate in near or full saturation. Each radiator radiates in one of a plurality of discrete, specified states. The radiated states from the radiators combine through far-field electromagnetic propagation and effectively sum at the receiver to mimic transmission from a single amplifier.
