Abstract:
1. A method, comprising: receiving an input signal, the input signal being a radio frequency (RF) signal or digital baseband information; separating the input signal into an in-phase (I) baseband signal and a quadrature (Q) baseband signal; decompose the I signal into an in-phase magnitude component and an in-phase phase component; decompose the Q signal into a quadrature magnitude component and a quadrature phase component; modulating the in-phase magnitude component and the in-phase phase component of the in-phase baseband signal; modulating the quadrature magnitude component and the quadrature phase component of the quadrature baseband signal; rectifying the in-phase magnitude component of the in-phase baseband signal; rectifying the quadrature magnitude component of the quadrature baseband signal; and amplifying the in-phase magnitude component and the first in-phase phase component to a first power amplifier, wherein the in-phase magnitude component and the first in-phase phase component are composed as an in-phase modulation on carrier, wherein said modulating is operated directly on the in-phase magnitude component of the decomposed in-phase signal, the in-phase phase component of the decomposed in-phase signal, the quadrature magnitude component of the decomposed quadrature signal and the quadrature phase component of the decomposed quadrature signal.
