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 Beamforming and Adaptive RF Chain Activation for Uplink Cell-Free Millimeter-Wave Massive MIMO Systems
Nhan Thanh Nguyen, Kyungchun Lee, Huaiyu Dai
In this work, we investigate hybrid analog-digital beamforming (HBF) architectures for uplink cell-free (CF) millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO)…
Intelligent Radio Signal Processing: A Survey
Quoc-Viet Pham, Nhan Thanh Nguyen, Thien Huynh-The +3
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…
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 (…
