Orthogonal time frequency space (OTFS) modulation outperforms orthogonal frequency
division multiplexing (OFDM) in high-mobility scenarios. One challenge for OTFS massive …

The joint design of hybrid beamforming matrices is conceived for multiuser mm-wave full-
duplex (FD) multiple-input multiple-output (MIMO) relay-aided systems in the presence of …

In mmWave massive multiple-input multiple-output (mMIMO) systems, hybrid (digital/analog)
structure has been a prevalent option to balance system cost and performance. To facilitate …

The space-air-ground integrated network (SAGIN) aims to provide seamless wide-area
connections, high throughput and strong resilience for 5G and beyond communications …

We investigate wideband uplink channel estimation for a multi-user (MU) multiple-input
single-output (MISO) OFDM system, in which the base station (BS) is equipped with an …

Radar sensing will be integrated into the 6G communication system to support various
applications. In this integrated sensing and communication system, a radar target may also …

Deep learning (DL)-based channel estimation has achieved remarkable success. However,
most existing works focus on the white Gaussian noise which are inapplicable for cell-edge …

Leveraging the concept of the electromagnetic signal and information theory, holographic
multiple-input multiple-output (MIMO) technology opens the door to an intelligent and …

In this paper, we propose an online training framework for mmWave Massive MIMO channel
