ABSTRACT:
A receiver for digital radio communications has an equalizer which is powered off for reduced power consumption when received radio waves undergo relatively small intersymbol interference. When intersymbol interference is significantly large, the equalizer is powered on to remove the intersymbol interference for better signal reception. The receiver has a signal quality decision circuit which powers on the equalizer when the quality of the received signal is poor, and powers off the equalizer when the quality of the received signal is good. The receiver consumes a relatively small amount of electric power overall.
