This paper designs a feedback beamformer (FBB) operating in combination with multiple low resolution ADCs of a MIMO communication system, to cancel the interfering users. Interference cancellation before the ADC operation saves the power spent in digitizing the interferers. We specify the necessary conditions required to cancel the interferers and propose a FBB design technique using only the training information from the desired user. We show using simulation results, that the FBB improves the dynamic range by a factor of three.
