Active IRS Aided Multiple Access for Energy-Constrained IoT Systems
Guangji Chen, Qingqing Wu, Chong He +3
We investigate the fundamental multiple access (MA) scheme in an active intelligent reflecting surface (IRS) aided energy-constrained Internet-of-Things (IoT) system, where an acti…
Cascaded Channel Estimation for RIS Assisted mmWave MIMO Transmissions
Yushan Liu, Shun Zhang, Feifei Gao +2
Channel estimation is challenging for the reconfigurable intelligence surface (RIS) assisted millimeter wave (mmWave) communications. Since the number of coefficients of the cascad…
Eudoxus: Characterizing and Accelerating Localization in Autonomous Machines
Yiming Gan, Bo Yu, Boyuan Tian +7
We develop and commercialize autonomous machines, such as logistic robots and self-driving cars, around the globe. A critical challenge to our -- and any -- autonomous machine is a…
Spectral-Energy Efficiency Trade-off-based Beamforming Design for MISO Non-Orthogonal Multiple Access Systems
Haitham Al-Obiedollah, Kanapathippillai Cumanan, Jeyarajan Thiyagalingam +4
Energy efficiency (EE) and spectral efficiency (SE) are two of the key performance metrics in future wireless networks, covering both design and operational requirements. For previ…
Resource Allocation Technique for Hybrid TDMA-NOMA System with Opportunistic Time Assignment
Xinchen Wei, Haitham Al-Obiedollah, Kanapathippillai Cumanan +4
In this paper, we develop a resource allocation technique for a hybrid time division multiple access (TDMA) - non-orthogonal multiple access (NOMA) system with opportunistic time a…
Autonomous Last-mile Delivery Vehicles in Complex Traffic Environments
Bai Li, Shaoshan Liu, Jie Tang +3
E-commerce has evolved with the digital technology revolution over the years. Last-mile logistics service contributes a significant part of the e-commerce experience. In contrast t…
