In this paper, we present a novel distributed UAVs beam reforming approach to dynamically
form and reform a space-selective beam path in addressing the coexistence with satellite …

In this paper, we investigate the beam domain statistical channel state information (CSI)
estimation for the two-dimensional (2D) beam-based statistical channel model (BSCM) in …

In this paper, we propose an information geometry approach (IGA) for signal detection (SD)
in ultra-massive multiple-input multiple-output (MIMO) systems. We formulate the signal …

This paper investigates the uplink channel estimation of the millimeter-wave (mmWave)
extremely large-scale multiple-input-multiple-output (XL-MIMO) communication system in …

Wireless positioning is crucial for Internet of Things (IoT) landscape, enhancing precision
and reliability in location-based services. This article addresses the challenges of existing …

Deep learning has significantly advanced three-dimensional computer vision applied to
point clouds. Nevertheless, the substantial consumption of time, storage, and energy …

This paper investigates the joint beam alignment and Doppler estimation (BADE) for fast
time-varying wideband millimeter-wave channels, which is essential for subsequent data …

In this two-part paper, we investigate the channel estimation for massive multiple-input
multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. In Part I …

This paper investigates the robust design of symbol-level precoding (SLP) for multiuser
multiple-input multiple-output (MIMO) downlink transmission with imperfect channel state …

In Part II of this two-part paper, we prove the convergence of the simplified information
geometry approach (SIGA) proposed in Part I. For a general Bayesian inference problem …
