ABSTRACT:
A method and device are set forth for, where a linear transmitter has inphase and quadrature modulation paths for an input signal and at least one open feedback signal path is provided, substantially correcting an initial phase relationship between an input signal having an input signal vector with a phase and a magnitude, and an input feedback signal having an input feedback signal vector with a phase and a magnitude. The present invention provides a more time-efficient phase correction to at least one feedback signal path.
