Analog Beamforming With Low Resolution Phase Shifters
IEEE Wireless Communications Letters, 2017In this letter, we consider analog beamforming using low resolution phase shifters for millimeter waves communications. We propose a hierarchical codebook design, where the beamforming vectors in the codebook are grouped into multiple levels and the preferred beamforming vector at each level is constructed to approximate an amplitude beamforming gain ...

Beamforming design with fully connected analog beamformer using deep learning
International Journal of Communication Systems, 2022SummaryBeamforming (BF) architecture, an emerging approach for large‐scale antenna arrays, is a key task for the next decade's communication systems. The proposed approach in millimeter wave transmission is a fully connected analog phase‐shifter‐based BF architecture with limited radio frequency chains and imperfect channel state information (CSI ...

Multi-User Analog Beamforming in Millimeter Wave MIMO Systems Based on Path Angle Information [PDF]
IEEE Transactions on Wireless Communications, 2019 We aim to design an analog-only beamforming scheme for downlink multi-user mm-wave systems to optimize the beamforming gain and the inter-user interference at the same time.

Hybrid analog digital beamforming
2022In recent years, two of the main trends in wireless communication have been higher carrier frequencies and larger antenna arrays. Each trend by itself allows for a significant gain in system performance, but they are difficult to combine. The former trend, higher carrier frequencies in the millimeter-wave (mm-wave) range, offers an unprecedented ...
