Pattern Zooming: Near-Field Wideband Beam Training with Wavenumber-Domain Codebook
Caihao Weng, Ying Wang, Xufeng Guo +2
Near-field beam training is essential for harvesting the high-gain potential of extremely large-scale multiple input multiple output systems. To reduce training overhead, existing…
Learning-Based Blockage-Resilient Beam Training in Near-Field Terahertz Communications
Caihao Weng, Yuqing Guo, Bowen Zhao +3
Terahertz (THz) band is considered a promising candidate to meet the high-throughput requirement for future sixth-generation (6G) wireless communications due to its ultrawide bandw…
An efficient branch-and-cut approach for the sequential competitive facility location problem under partially binary rule
Yu-Qi Guo, Yan-Ru Wang, Wei-Kun Chen +1
We investigate the sequential competitive facility location problem (SCFLP) under partially binary rule where two companies sequentially open a limited number of facilities to maxi…
Channel Estimation for Holographic MIMO: Wavenumber-Domain Sparsity Inspired Approaches
Yuqing Guo, Yuanbin Chen, Ying Wang
This paper investigates the sparse channel estimation for holographic multiple-input multiple-output (HMIMO) systems. Given that the wavenumber-domain representation is based on a…
Sparse Recovery for Holographic MIMO Channels: Leveraging the Clustered Sparsity
Yuqing Guo, Xufeng Guo, Yuanbin Chen +1
Envisioned as the next-generation transceiver technology, the holographic multiple-input-multiple-output (HMIMO) garners attention for its superior capabilities of fabricating elec…
