A 23-to-30GHz hybrid beamforming MIMO receiver array with closed-loop multistage front-end beamformers for full-FoV dynamic and autonomous unknown signal tracking and blocker rejection

Millimeter-wave massive MIMOs leverage large array size to enhance the link budget and spatial selectivity, but their resulting narrow beamwidth substantially complicates the transmitter-receiver (TX-RX) alignment. Unlike most existing “static” applications (e.g., mm-wave HDTV transmission), many future mm-wave links will operate in highly “dynamic” environments, such as wireless AR/VR and vehicle-/drone-/machine-based links, necessitating rapid and precise beam-forming/-tracking for high link reliability and low latency. Densely deployed mm-wave nodes will also result in future congested/contested environments, requiring spatially tracking/rejecting unknown blockers (unknown frequency, angle-of-arrival AoA, or modulation).
