Jun 04, 2018 · Beamforming Beamforming networks (BFN) are used to combine signals from small antennae into a pattern that is more directional than each individual antenna alone because of the array factor. Beamformers are used in radar and communications. Sep 01, 2005 · Adaptive beamforming can be undertaken in the conventional covariance domain or, alternatively, the data domain via QR decomposition, which has been shown to be more suitable for FPGA implementation and more robust to reduced numerical precision, as a matrix inversion is not required.
Beamforming is a critical and natural solution component for 60 GHz radios due to the increased signal attenuation that occurs as a consequence of the very small wavelength (mm-length) at these frequencies. An adaptive beamformer is a system that performs adaptive spatial signal processing with an array of transmitters or receivers. The signals are combined in a manner which increases the signal strength to/from a chosen direction. Signals to/from other directions are combined in a benign or destructive manner, resulting in degradation of the signal to/from the undesired direction.
