Abstract: Techniques are disclosed to address issues related to the computation of channel state information (CSI) and angular spectrum (AS) to perform beamforming. The CSI and AS, as well as various statistical channel parameters of a wireless channel, may be computed using different techniques, which include the use of domain knowledge enhanced neural networks (DKE-NNs). The CSI and AS may be further utilized to perform beamforming using various techniques. One of these techniques may include the implementation of eigen beamforming, which provides artificially generated power at locations within the AS that are identified with estimated eigenvector beam locations. As a result of the artificially-generated power, the resulting vector decomposition used to provide the beamforming weights results in widened eigenvector beams.
