Title
(EN) A BEAMFORMING RECEIVER
(FR) RÉCEPTEUR DE FORMATION DE FAISCEAU
Abstract
(EN)
A beamforming receiver 100 for receiving multiple radio signals and generating multiple output beam signals is disclosed. The beamforming receiver (100) comprises multiple beam parameter inputs (130) to receive multiple beam parameters and an element array (110) comprising a plurality of elements (120). The beamforming receiver 100 further comprises a loading unit 140 coupled to each element 120 in the element array 1 10. The beamforming receiver 100 further comprises a reference clock generating and splitting circuit 150 to generate and distribute reference clock signals for each element 120.
