Modular Binary Tree Architecture for Distributed Large Intelligent Surface
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021Large intelligent surface (LIS) is a technology that extends massive MIMO by considering an even greater number of antennas distributed throughout vast areas. In order to be able to implement this technology, it is crucial to consider decentralized architectures so as to make the whole system scalable.

Performance Analysis for Large Intelligent Surfaces enabled MIMO Networks
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020This paper conceive a large intelligent surface (LIS)aided multiple-input multiple-output network for providing wireless services to randomly roaming users. The network performance is analyzed by utilizing stochastic geometry tools. We aim for serving multiple users by jointly designing the passive beamforming weight at LISs and detection weight ...

Cooperative Beamforming for Large Intelligent Surface Assisted Symbiotic Radios
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020In this paper, we investigate a large intelligent surface (LIS) assisted symbiotic radio (SR) system, in which a LIS device, operating as an Internet-of-Things (IoT) device, exploits the signal from a primary transmitter (PT) as its communication carrier to achieve its own information transmission, and concurrently serves as a desirable additional link

Achievable Rate with Correlated Hardware Impairments in Large Intelligent Surfaces
2019 IEEE 8th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2019Large intelligent surface (LIS) is a new technology yet to be developed. However, this technology is likely to be implemented using cheap components so as to facilitate its deployment. Therefore, we can expect a performance degradation due to hardware impairments.

Channel Estimation for Ambient Backscatter Communications with Large Intelligent Surface
2019 11th International Conference on Wireless Communications and Signal Processing (WCSP), 2019In this paper, we investigate the channel estimation problem for ambient backscatter communication system where the backscatter device utilizes large intelligent surface (LIS). For the considered LIS-assisted system, a general system model for ambient backscatter with LIS features is presented.
