WiDRa -- Enabling Millimeter-Level Differential Ranging Accuracy in Wi-Fi Using Carrier Phase
Vishnu V. Ratnam, Bilal Sadiq, Hao Chen +5
Although Wi-Fi is an ideal technology for many ranging applications, the performance of current methods is limited by the system bandwidth, leading to low accuracy of m. F…
Joint Phase-Time Arrays: A Paradigm for Frequency-Dependent Analog Beamforming in 6G
Vishnu V. Ratnam, Jianhua Mo, Ahmad AlAmmouri +4
Hybrid beamforming is an attractive solution to build cost-effective and energy-efficient transceivers for millimeter-wave and terahertz systems. However, conventional hybrid beamf…
Beam Codebook Design for 5G mmWave Terminals
Jianhua Mo, Boon Loong Ng, Sanghyun Chang +6
A beam codebook of 5G millimeter wave (mmWave) for data communication consists of multiple high-peak-gain beams to compensate the high pathloss at the mmWave bands. These beams als…
Grip-Aware Analog mmWave Beam Codebook Adaptation for 5G Mobile Handsets
Ahmad AlAmmouri, Jianhua Mo, Boon Loong Ng +2
This paper studies the effect of the user hand grip on the design of beamforming codebooks for 5G millimeter-wave (mmWave) mobile handsets. The high-frequency structure simulator (…
