Machine-Learning Beam Tracking and Weight Optimization for mmWave Multi-UAV Links
Hsiao-Lan Chiang, Kwang-Cheng Chen, Wolfgang Rave +2
Millimeter-wave (mmWave) hybrid analog-digital beamforming is a promising approach to satisfy the low-latency constraint in multiple unmanned aerial vehicles (UAVs) systems, which…
Time-Domain Multi-Beam Selection and Its Performance Improvement for mmWave Systems
Hsiao-Lan Chiang, Wolfgang Rave, Gerhard Fettweis
Multi-beam selection is one of the crucial technologies in hybrid beamforming systems for frequency-selective fading channels. Addressing the problem in the frequency domain facili…
Frequency-Selective Hybrid Beamforming Based on Implicit CSI for Millimeter Wave Systems
Hsiao-Lan Chiang, Wolfgang Rave, Tobias Kadur +1
Hybrid beamforming is a promising concept to achieve high data rate transmission at millimeter waves. To implement it in a transceiver, many references optimally adapt to a high-di…
Impact of Major RF Impairments on mm-wave Communications using OFDM Waveforms
Yaning Zou, Per Zetterberg, Ulf Gustavsson +5
In this paper, we study the joint impact of three major RF im-pairments, namely, oscillator phase noise, power amplifier non-linearity and I/Q imbalance on the performance of a mm-…
Analog Beamsteering for Flexible Hybrid Beamforming Design in Mmwave Communications
Yaning Zou, Wolfgang Rave, Gerhard Fettweis
In this paper, we propose an analog beamsteering approach for enabling flexible hybrid beamforming design that can achieve performance close to singular value decomposition (SVD) b…
