Abstract: Training beam design for channel estimation with infinite-resolution and low-resolution phase shifters (PSs) in hybrid analog-digital milimeter wave (mmWave) massive multiple-input ...
The cross-car beam runs behind the dashboard across the width of the vehicle and serves as a vital structural support, contributing to passenger safety and providing mounting points for airbags.
Abstract: For high-speed train (HST) millimeter wave (mmWave) communications, the use of narrow beams with small beam coverage needs frequent beam switching, while wider beams with small beam gain ...
