Joint Beamforming Design for RIS-enabled Integrated Positioning and Communication in Millimeter Wave Systems

Autor: Sun, Junchang, Ma, Shuai, Li, Shiyin

Integrated positioning and communication (IPAC) system and reconfigurable intelligent surface (RIS) are both considered to be key technologies for future wireless networks. Therefore, in this paper, we propose a RIS-enabled IPAC scheme with the milli

Robust Power Allocation for UAV-aided ISAC Systems with Uncertain Location Sensing Errors

Autor: Sun, Junchang, Ma, Shuai, Yang, Ruixin, Tingting, Yang, Li, Shiyin

Unmanned aerial vehicle (UAV) holds immense potential in integrated sensing and communication (ISAC) systems for the Internet of Things (IoT). In this paper, we propose a UAV-aided ISAC framework and investigate three robust power allocation schemes.

Robust Beamforming for Localization-Aided Millimeter Wave Communication Systems

Autor: Sun, Junchang, Ma, Shuai, Li, Shiyin, Yang, Ruixin, Min, Minghui, Seco-Granados, Gonzalo

In this letter, we investigate a robust beamforming problem for localization-aided millimeter wave (mmWave) communication systems. To handle this problem, we propose a novel restriction and relaxation (R&R) method. The proposed R&R method aims at min

Covert Beamforming Design for Intelligent Reflecting Surface Assisted IoT Networks

Autor: Ma, Shuai, Zhang, Yunqi, Li, Hang, Sun, Junchang, Shi, Jia, Zhang, Han, Shen, Chao, Li, Shiyin

In this paper, we consider covert beamforming design for intelligent reflecting surface (IRS) assisted Internet of Things (IoT) networks, where Alice utilizes IRS to covertly transmit a message to Bob without being recognized by Willie. We investigat
