Tensor-based Multi-dimensional Wideband Channel Estimation for mmWave Hybrid Cylindrical Arrays
Zhipeng Lin, Tiejun Lv, Wei Ni +2
Channel estimation is challenging for hybrid millimeter wave (mmWave) large-scale antenna arrays which are promising in 5G/B5G applications. The challenges are associated with angu…
Analysis and Optimization of Service Delay for Multi-quality Videos in Multi-tier Heterogeneous Network with Random Caching
Xuewei Zhang, Tiejun Lv, Yuan Ren +2
Aiming to minimize service delay, we propose a new random caching scheme in device-to-device (D2D)-assisted heterogeneous network. To support diversified viewing qualities of multi…
Complex ResNet Aided DoA Estimation for Near-Field MIMO Systems
Yashuai Cao, Tiejun Lv, Zhipeng Lin +2
The near-field effect of short-range multiple-input multiple-output (MIMO) systems imposes many challenges on direction-of-arrival (DoA) estimation. Most conventional scenarios ass…
Nested Hybrid Cylindrical Array Design and DoA Estimation for Massive IoT Networks
Zhipeng Lin, Tiejun Lv, Wei Ni +2
Reducing cost and power consumption while maintaining high network access capability is a key physical-layer requirement of massive Internet of Things (mIoT) networks. Deploying a…
Learning-Based Multi-Channel Access in 5G and Beyond Networks with Fast Time-Varying Channels
Shaoyang Wang, Tiejun Lv, Xuewei Zhang +2
We propose a learning-based scheme to investigate the dynamic multi-channel access (DMCA) problem in the fifth generation (5G) and beyond networks with fast time-varying channels w…
Sum Rate Maximization for Reconfigurable Intelligent Surface Assisted Device-to-Device Communications
Yashuai Cao, Tiejun Lv
In this letter, we propose to employ reconfigurable intelligent surfaces (RISs) for enhancing the D2D underlaying system performance. We study the joint power control, receive beam…
