Spectral Efficiency Optimization for Hybrid Relay-Reflecting Intelligent Surface
Nhan Thanh Nguyen, Quang-Doanh Vu, Kyungchun Lee +1
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 re…
Hybrid Relay-Reflecting Intelligent Surface-Assisted Wireless Communication
Nhan Thanh Nguyen, Quang-Doanh Vu, Kyungchun Lee +1
Reconfigurable intelligent surface (RIS) has emerged as a cost- and energy-efficient solution to enhance the wireless communication capacity. However, recent studies show that a ve…
Application of Deep Learning to Sphere Decoding for Large MIMO Systems
Nhan Thanh Nguyen, Kyungchun Lee, Huaiyu Dai
Although the sphere decoder (SD) is a powerful detector for multiple-input multiple-output (MIMO) systems, it has become computationally prohibitive in massive MIMO systems, where…
Hybrid Combining Based on Constant Phase Shifters and Active/Inactive Switches
Eduard E. Bahingayi, Kyungchun Lee
In this paper, we propose a new hybrid analog and digital combining architecture for millimeter wave (mmWave) multi-user multiple-input multiple-output (MU-MIMO) systems. The propo…
Learning-Aided Deep Path Prediction for Sphere Decoding in Large MIMO Systems
Doyeon Weon, Kyungchun Lee
In this paper, we propose a novel learning-aided sphere decoding (SD) scheme for large multiple-input--multiple-output systems, namely, deep path prediction-based sphere decoding (…
Groupwise Neighbor Examination for Tabu Search Detection in Large MIMO systems
Nhan Thanh Nguyen, Kyungchun Lee
In the conventional tabu search (TS) detection algorithm for multiple-input multiple-output (MIMO) systems, the metrics of all neighboring vectors are computed to determine the bes…
