Joint Active and Passive Beamforming for IRS-Aided Wireless Energy Transfer Network Exploiting One-Bit Feedback

no code implementations8 Apr 2024 Taotao Ji, Meng Hua, ChunGuo Li, Yongming Huang, Luxi Yang

To reap the active and passive beamforming gain in an intelligent reflecting surface (IRS)-aided wireless network, a typical way is to first acquire the channel state information (CSI) relying on the pilot signal, and then perform the joint beamforming design.

Near-Field Channel Estimation for Extremely Large-Scale Array Communications: A model-based deep learning approach

no code implementations28 Nov 2022 Xiangyu Zhang, Zening Wang, Haiyang Zhang, Luxi Yang

In particular, we first formulate the XL-MIMO near-field channel estimation task as a compressed sensing problem using the spatial gridding-based sparsifying dictionary, and then solve the resulting problem by applying the Learning Iterative Shrinkage and Thresholding Algorithm (LISTA).

Joint User Association and Power Allocation in Heterogeneous Ultra Dense Network via Semi-Supervised Representation Learning

no code implementations29 Mar 2021 Xiangyu Zhang, Zhengming Zhang, Luxi Yang

We model the HUDNs as a heterogeneous graph and train a Graph Neural Network (GNN) to approach this representation function by using semi-supervised learning, in which the loss function is composed of the unsupervised part that helps the GNN approach the optimal representation function and the supervised part that utilizes the previous experience to reduce useless exploration.
