Abstract
Aspects of a method and system for polar modulating OFDM signals with discontinuous phase may include amplifying a normalized OFDM signal via a plurality of amplifiers such that a combined gain of the plurality of amplifiers comprises a coarse amplitude gain and an amplitude offset gain. A gain of one or more of the plurality of amplifiers may be adjusted to set the coarse amplitude gain, and a gain of one or more remaining ones of the plurality of amplifiers may be adjusted to set the amplitude offset gain adaptively and/or dynamically. The setting of the coarse amplitude gain and/or the amplitude offset gain may be adjusted dynamically and/or adaptively via an amplitude control.
