ABSTRACT
ONE of the simplest modulation schemes is amplitude modulation, which is normally just abbreviated as AM. The commercial AM broadcast radio stations in the United States use a version of AM called double sideband large carrier (DSB-LC), sometimes also called double sideband with carrier (DSB-WC). See [64,85] for some general theoretical background on amplitude modulated signals, and [86,87] for more DSP-specific background on AM communications.
