A communication system using adaptive sample rate reduction (ASRR) is disclosed. The system includes a digital front end (DFE) and a radio frequency (RF) interface. The DFE is configured to receive a baseband signal, identify reduced performance parameters for the baseband signal, reduce a sampling rate for the baseband signal based on the reduced performance parameters and generate a digital interface signal using the reduced sampling rate. The RF interface is configured to generate an analog TX signal from the digital interface signal.
