DRL-Based Sidelobe Suppression for Multi-focus Reconfigurable Intelligent Surface

no code implementations24 Dec 2023 Wei Wang, Peizheng Li, Angela Doufexi, Mark A Beach

Reconfigurable intelligent surface (RIS) technology is receiving significant attention as a key enabling technology for 6G communications, with much attention given to coverage infill and wireless power transfer.

A DRL-based Reflection Enhancement Method for RIS-assisted Multi-receiver Communications

no code implementations11 Sep 2023 Wei Wang, Peizheng Li, Angela Doufexi, Mark A Beach

In reconfigurable intelligent surface (RIS)-assisted wireless communication systems, the pointing accuracy and intensity of reflections depend crucially on the 'profile,' representing the amplitude/phase state information of all elements in a RIS array.

PowerBEV: A Powerful Yet Lightweight Framework for Instance Prediction in Bird's-Eye View

1 code implementation19 Jun 2023 Peizheng Li, Shuxiao Ding, Xieyuanli Chen, Niklas Hanselmann, Marius Cordts, Juergen Gall

Accurately perceiving instances and predicting their future motion are key tasks for autonomous vehicles, enabling them to navigate safely in complex urban traffic.

Deep Transfer Learning for WiFi Localization

no code implementations8 Mar 2021 Peizheng Li, Han Cui, Aftab Khan, Usman Raza, Robert Piechocki, Angela Doufexi, Tim Farnham

Finally, an ablation study of the training dataset shows that, in both office and sport hall scenarios, after reusing the feature extraction layers of the base model, only 55% of the training data is required to obtain the models' accuracy similar to the base models.

Wireless Localisation in WiFi using Novel Deep Architectures

no code implementations16 Oct 2020 Peizheng Li, Han Cui, Aftab Khan, Usman Raza, Robert Piechocki, Angela Doufexi, Tim Farnham

Meanwhile, using a well-organised architecture, the neural network models can be trained directly with raw data from the CSI and localisation features can be automatically extracted to achieve accurate position estimates.
