ABSTRACT:
A receiver includes an antenna array, a plurality of phase shifters, a matrix module, a low noise amplifier module, and a down conversion module. The antenna array is operably coupled to receive an inbound wireless signal. The plurality of phase shifters is operably coupled to the antenna array and to produce a plurality of phase shifted inbound wireless signals. The matrix module is operably coupled to beamform the plurality of phase shifted inbound wireless signals to produce a plurality of beamformed and phase shifted inbound wireless signals. The low noise amplifier module is operably coupled to amplify one or more of the plurality of beamformed and phase shifted inbound wireless signals to produce one or more amplified inbound signals. The down conversion module is operably coupled to convert the one or more amplified inbound wireless signals into one or more baseband or near baseband signals.
