Propagation Path Loss Models in Forest Scenario at 605 MHz
Zhe Xiao, Shu Sun, Zhenyu Liu +4
When signals propagate through forest areas, they will be affected by environmental factors such as vegetation. Different types of environments have different influences on signal…
Hybrid Spherical- and Planar-Wave Channel Modeling and Estimation for Terahertz Integrated UM-MIMO and IRS Systems
Yuhang Chen, Renwang Li, Chong Han +2
Integrated ultra-massive multiple-input multiple-output (UM-MIMO) and intelligent reflecting surface (IRS) systems are promising for 6G and beyond Terahertz (0.1-10 THz) communicat…
Channel Eigenvalues and Effective Degrees of Freedom of Reconfigurable Intelligent Surfaces
Shu Sun
As a promising candidate technology for the next-generation wireless communications, reconfigurable intelligent surface (RIS) has gained tremendous research interest in both the ac…
Channel Estimation for Reconfigurable Intelligent Surface-Assisted Wireless Communications Considering Doppler Effect
Shu Sun, Hangsong Yan
In wireless systems aided by reconfigurable intelligent surfaces (RISs), channel state information plays a pivotal role in achieving the performance gain of RISs. Mobility renders…
Practical Link Adaptation Algorithm with Power Density Offsets for 5G Uplink Channels
Shu Sun, Sungho Moon, Jong-Kae Fwu
This letter proposes a pragmatic link adaptation algorithm considering power density offsets (PDOs) for next-generation uplink wireless channels. The proposed algorithm consists of…
Hybrid Beamforming for 5G Millimeter-Wave Multi-Cell Networks
Shu Sun, Theodore S. Rappaport, Mansoor Shafi
Multi-cell wireless systems usually suffer both intra-cell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi…
