Many modulation techniques have been specifically designed to have constant envelope modulation, i.e., the minimum possible crest factor of 1:1. In general, modulation techniques that have smaller crest factors usually transmit more bits per second than modulation techniques that have higher crest factors. This is because: 1. any given linear amplifier has some "peak output power"—some maximum possible instantaneo… WebPAPR reduction approaches are categorized into three broad classes: signal distortion, coding schemes, symbol scrambling techniques, and Tone Reservation (TR).
