Abstract :
We present two-antenna receiver architecture with analog beamforming capability while allowing for multiple data-stream communication, as required in a genuine MIMO receiver. The proposed superheterodyne architecture advantageously combines the concepts of analog beamforming and MIMO communication, leading to relaxed noise and linearity requirements as well as lower power consumption for the IF filters and data converters.
