摘要:
Systems and methods are provided for providing a hybrid signal having a reduced crest factor. An analog exciter generates an analog signal having an associated phase. A digital exciter generates a digital signal that assumes one of a plurality of vector states at discrete sampling times associated with the hybrid signal. Each of the plurality of vector states has an associated phase. The digital signal and the analog signal are combined to provide the hybrid signal. The hybrid signal is compressed maximally when the digital signal assumes a vector state that is in phase with the analog signal.
