Advanced Hybrid Beamforming Design for MIMO Systems

2018 IEEE 10th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2018
One of the fundamental problems for hybrid beamformer design in MIMO systems is that, in Singular-Value-Decomposition (SVD) based beamforming, the analog beamformer is limited to constant modulus. In order to solve this issue, an algorithm is proposed in this paper. Specifically, the parallel data streams are expressed mathematically, and then the math

Varying the Beamwidth of Hybrid Beamforming for mmWave Communications

2019 IEEE 40th Sarnoff Symposium, 2019
Availability of large array usage in millimeter wave communications gives the opportunity to create narrow beams that yield to high antenna gains. However, in some cases, wider beams are of interest in order to increase the coverage area or reduce the outages caused by the channel variations.

Hybrid beamforming for massive MIMO

2018
Deployed with a large number of antenna elements, massive multiple-input-multiple-output (MIMO) systems will be an important component of next generation wireless systems, because they provide tremendous increase of spectral efficiency. However, two major challenges hinder the implementation of massive MIMO in a practical system.
