Deep Unfolding-Powered Analog Beamforming for In-Band Full-Duplex [PDF]
IEEE Open Journal of the Communications SocietyIn-band full-duplex (IBFD) can double the spectral efficiency of wireless communications systems. However, its major drawback is the self-interference, which interferes with the desired signal at the terminal.

A Robust Secure Hybrid Analog and Digital Receive Beamforming Scheme for Efficient Interference Reduction [PDF]
IEEE Access, 2019 Medium-scale or large-scale receive antenna array with digital beamforming can be employed at receiver to make a significant interference reduction but leads to expensive cost and high complexity of the RF-chain circuit.

Vector Modulator-Based Analog Beamforming Using the Least Euclidean Distance Criterion [PDF]
IEEE Access, 2021 In traditional multiple-input multiple-output (MIMO) receivers, radio frequency (RF) front-ends are exposed to interference as no analog spatial filtering is employed before the digital beamforming stage.

Wideband analog and digital beamforming [PDF]
2009 9th International Conference on Telecommunication in Modern Satellite, Cable, and Broadcasting Services, 2009 High quality beamforming is necessary for the integrity of phased arrays and accuracy of monopulse direction finding systems. Traditionally, beamformers are realized as hybrid or monolithically integrated analog sub-systems. Their wideband operation is plagued by higher loss, amplitude and phase misbalances, weight, complex integration, etc.
