A low complexity hybrid combiner design for the ill‐conditioned multiuser mmWave massive MIMO uplink

IET Communications, 2021
This paper presents a simple and robust hybrid combiner for the multiuser massive multiple‐input multiple‐output (MIMO) uplink. The hybrid beamforming is used in massive MIMO systems to reduce the number of radio frequency chains.

Vector Modulator-Based Analog Beamforming Using the Least Euclidean Distance Criterion

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.

Multiuser hybrid analog/digital beamforming for relatively large-scale antenna arrays

, 2013
Power consumption and costs of the analog front-end (AFE) chains are often not negligible for large-scale antenna array systems. A low-complexity hardware architecture is to use a number of AFE chains that is less than the number of the antennas ...

A Robust Secure Hybrid Analog and Digital Receive Beamforming Scheme for Efficient Interference Reduction

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.
