Method And System For Hybrid Radio Frequency Digital Beamforming

Abstract

Methods and systems for hybrid radio frequency digital beamforming may include, in an electronic device comprising an antenna array including antennas arranged along first and second directions, beamforming signals in an analog domain along the first direction of the antenna array and in a digital domain along the second direction of the antenna array. The antenna array may include subsets of antennas, where each subset has a system-on-chip (SOC) with analog and digital beamforming circuitry. Signals may be beamformed in the analog domain by amplifying signals received by the antenna array using a configurable gain and shifting the phase of at least one of the amplified signals. The phase-shifted signals may be summed and converted to a digital signal. A frequency-dependent coefficient may be applied to the digital signal. The antenna array may have a fewer number of antennas along the first direction as compared to along the second direction.
