The initial access in Millimeter wave (mmWave) 5G communications is very challenging and
time consuming. In general, mmWave and terahertz communications require the use of …

This paper proposes a deep learning approach to the adaptive and sequential beamforming
design problem for the initial access phase in a mmWave environment with a single-path …

Beam alignment is an important task for millimeter-wave (mmWave) communication,
because constructing aligned narrow beams both at the transmitter (Tx) and the receiver …

We consider the problem of active sensing and sequential beam tracking at mmWave
frequencies and above. We focus on the setting of aerial communications between a quasi …

With abundant bandwidth resources, terahertz communications are considered one of the
key technologies to meet the requirement for high data-rate transmission in the future. In …

The initial setup at millimeter-wave channels is especially challenging due to the severe
propagation loss imposed on the channel gains. To overcome this loss, it is common to use …

Communication in Millimeter wave (mmWave) band relies on narrow beams due to
directionality, high path loss, and shadowing. One can use beam alignment (BA) techniques …

High-frequency bands such as millimeter-wave and terahertz require narrow beams due to
path loss and shadowing. Beam alignment (BA) methods allow the transceivers to adjust the …

Narrow beams are key to wireless communications in millimeter wave frequency bands.
Beam alignment (BA) allows the base station (BS) to adjust the direction and width of the …

We consider the problem of active and sequential beam tracking at mmWave frequencies
and above. We focus on the dynamic scenario of a UAV to UAV communications where we …
