Adaptive digital beamforming receiver for improving signal reception quality

摘要

There is disclosed an apparatus and method for improving signal reception in a signal receiver. The apparatus comprises a beamforming circuit and a decision feedback equalizer circuit. The beamforming circuit comprises two circuit branches with each circuit branch having a radio frequency (RF) tuner capable of being coupled to an antenna, an intermediate frequency (IF) mixer, and a feedforward equalizer circuit and an adder circuit. In the decision feedback equalizer circuit a decision device that is coupled to the output of said adder circuit modifies equalizer coefficients in said feedforward equalizer circuits to reduce an interfering signal by electronically forming a null in the direction of the interfering signal.
