Lightweight Deep Learning Based Channel Estimation for Extremely Large-Scale Massive MIMO Systems

1 code implementation14 Feb 2024 Shen Gao, Peihao Dong, Zhiwen Pan, Xiaohu You

Extremely large-scale massive multiple-input multiple-output (XL-MIMO) systems introduce the much higher channel dimensionality and incur the additional near-field propagation effect, aggravating the computation load and the difficulty to acquire the prior knowledge for channel estimation.

Deep Multi-Stage CSI Acquisition for Reconfigurable Intelligent Surface Aided MIMO Systems

no code implementations23 Apr 2021 Shen Gao, Peihao Dong, Zhiwen Pan, Geoffrey Ye Li

This article aims to reduce huge pilot overhead when estimating the reconfigurable intelligent surface (RIS) relayed wireless channel.

Reinforcement Learning Based Cooperative Coded Caching under Dynamic Popularities in Ultra-Dense Networks

no code implementations8 Mar 2020 Shen Gao, Peihao Dong, Zhiwen Pan, Geoffrey Ye Li

For ultra-dense networks with wireless backhaul, caching strategy at small base stations (SBSs), usually with limited storage, is critical to meet massive high data rate requests.
