Near-field Communications with Extremely Large-Scale Uniform Arc Arrays: Channel Modelling and Performance Analysis
Guoyu Li, Changsheng You, Guanyu Shang +1
In this letter, we propose a new conformal array architecture, called extremely large-scale uniform arc array (XL-UAA), to improve near-field communication performance. Specificall…
A Homogeneous Graph Neural Network for Precoding and Power Allocation in Scalable Wireless Networks
Mingjun Sun, Shaochuan Wu, Haojie Wang +3
Deep learning is widely used in wireless communications but struggles with fixed neural network sizes, which limit their adaptability in environments where the number of users and…
Asynchronous Cell-Free Massive MIMO-OFDM: Mixed Coherent and Non-Coherent Transmissions
Guoyu Li, Shaochuan Wu, Changsheng You +2
In this letter, we analyze the performance of mixed coherent and non-coherent transmissions approach, which can improve the performance of cell-free multiple-input multiple-output…
Power Allocation for Cell-Free Massive MIMO ISAC Systems with OTFS Signal
Yifei Fan, Shaochuan Wu, Xixi Bi +1
Applying integrated sensing and communication (ISAC) to a cell-free massive multiple-input multiple-output (CF mMIMO) architecture has attracted increasing attention. This approach…
