Dual-Polarized IRS-Assisted MIMO Network
For \(N = 50\), DP-IRS achieves 24. 8 \%, 28. 2 \%, and 30. 3 \% improvements in SE for \({4} \times {4}\), \({8} \times {8}\), and \({16} \times {16}\) MIMO, respectively, compared to S-IRS.
Spectral Efficiency Optimization for Hybrid Relay-Reflecting Intelligent Surface
We propose a novel concept of hybrid relay-reflecting intelligent surface (HR-RIS), in which a single or few elements are deployed with power amplifiers (PAs) to serve as active relays, while the remaining elements only reflect the incident signals.
Hybrid Relay-Reflecting Intelligent Surface-Assisted Wireless Communication
The simulation results show that a significant improvement in both the spectral efficiency (SE) and energy efficiency (EE) with respect to the conventional RIS-aided system can be attained by the proposed schemes, especially, by the dynamic HR-RIS.
Intelligent Radio Signal Processing: A Survey
Intelligent signal processing for wireless communications is a vital task in modern wireless systems, but it faces new challenges because of network heterogeneity, diverse service requirements, a massive number of connections, and various radio characteristics.
Learning-Aided Deep Path Prediction for Sphere Decoding in Large MIMO Systems
In this scheme, we employ a neural network (NN) to predict the minimum metrics of the ``deep'' paths in sub-trees before commencing the tree search in SD.
Deep Learning-Aided Tabu Search Detection for Large MIMO Systems
Then, we propose the DL-aided TS algorithm, in which the initial solution is approximated by the proposed FS-Net.
