Precision-Aware Hierarchical Spectrum Search for Finite-Precision MUSIC DOA Estimation
Linyun Yue, Chuang Yang, Jierui Chen +1
Dense-grid spectrum search is computationally costly for multiple signal classification (MUSIC) direction-of-arrival (DOA) estimation, and low-precision evaluation can introduce nu…
Channel Modeling of Satellite-to-Underwater Laser Communication Links: An Analytical-Monte Carlo Hybrid Approach
Zhixing Wang, Renzhi Yuan, Haifeng Yao +2
Channel modeling for satellite-to-underwater laser communication (StULC) links remains challenging due to long distances and the diversity of the channel constituents. The StULC ch…
Joint Communication and Radar Sensing for Terahertz Space-Air-Ground Integrated Networks (SAGIN)
Chong Han, Weijun Gao, Zhepu Yin +3
The transition from isolated systems to integrated solutions has driven the development of space-air-ground integrated networks (SAGIN) as well as the integration of communication…
Sensing-Assisted Beam Tracking with Real-Time Beamwidth Adaptation for THz Communications
Wuhan Chen, Yuheng Fan, Chuang Yang +1
Terahertz (THz) communications, with their substantial bandwidth, are essential for meeting the ultra-high data rate demands of emerging high-mobility scenarios such as vehicular-t…
Hybrid Precoding With Low-Resolution PSs for Wideband Terahertz Communication Systems in The Face of Beam Squint
Yang Wang, Chuang Yang, Mugen Peng
Terahertz (THz) communication is considered one of the most critical technologies for 6G because of its abundant bandwidth. To compensate the high propagation of THz, analog/digita…
Turbulent Multiple-Scattering Channel Modeling for Ultraviolet Communications: A Monte-Carlo Integration Approach
Renzhi Yuan, Xinyi Chu, Tao Shan +2
Modeling of multiple-scattering channels in atmospheric turbulence is essential for the performance analysis of long-distance non-line-of-sight (NLOS) ultraviolet (UV) communicatio…
