On Outage-Based Beamforming Design for Dual-Functional Radar-Communication 6G Systems [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2022
This article studies and derives beamforming design in a dual-functional radar-communication (DFRC) multiple-input-multiple-output system. We focus on a scenario, where the DFRC base station communicates with downlink communication users, with imperfect ...

Broadband Beamforming Using the Least Square Method Improved via Adaptive Diagonal Loading [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2023
The least square method (LSM) is a commonly used beamforming method. However, it limits the beamforming frequency bandwidth and is vulnerable to noise; therefore, diagonal loading is used to overcome these limitations.

A leakage‐based hybrid beamforming design for multi‐user mmWave massive MIMO systems

open access: yesIET Communications, Volume 17, Issue 1, Page 110-120, January 2023., 2023
Abstract In massive multiple‐input multiple‐output systems, hybrid beamforming (HBF) is an attractive technique due to its excellent tradeoff between system performance and hardware implementation cost. In this paper, the signal‐to‐leakage‐plus‐noise ratio is considered as the optimization criterion and investigate the HBF design for multi‐user ...

Robust transmission design for artificial noise aided multiuser broadcast system in inaccurate channel state information scenario with users of different importance

open access: yesIET Communications, Volume 17, Issue 2, Page 171-182, January 2023., 2023
Abstract In this article, robust beamforming (BF) and artificial noise (AN) design method is proposed for multiuser broadcast secure transmission under secrecy outage probability (SOP) constraints. A special scenario is assumed that the transmitter cannot obtain the accurate channel state information (CSI) of the users' channel, and different users ...

High‐gain ultra‐wideband quasi‐conical beam Fabry‐Perot antenna based on beam switching

open access: yesIET Microwaves, Antennas &Propagation, Volume 17, Issue 1, Page 75-82, January 2023., 2023
To solve the contradiction between the high gain and wide coverage, the concept of the quasi‐conical beam is proposed by using the high‐gain pencil beam electrically switching along a cone to make full use of time redundancy. In a periphery‐fed Fabry‐Perot (FP)‐type multi‐beam antenna, the electrically switching is used to activate the different port ...
