AbstractThe non-linear operating characteristics of efficient, high-powered amplifiers has motivated the development of constant envelope signaling schemes for satellite, mobile, and range communications. As such applications face demands for greater spectral efficiency, it has become useful to re-examine non-linear amplifiers with respect to spectral regrowth of filtered signals, and the performance of non-constant envelope signaling. This paper examines the use of amplifier models, empirical measurements, and software tools in the development of spectrally efficient QAM signal schemes.
