User Mobility Demands Near-Field Communications in Terahertz Band Wireless Networks Beyond 6G
Peng Zhang, Vitaly Petrov, Arjun Singh +2
Near-field propagation is often unavoidable at terahertz (THz) frequencies due to the large apertures needed for sufficient array gain, yet near-field operation complicates practic…
Near-field Boundary Distance in mmWave and THz Communications with Misaligned Antenna Arrays
Peng Zhang, Vitaly Petrov, Emil Björnson
Wireless communications in the millimeter wave (mmWave) and terahertz (THz) spectrum allow harnessing large frequency bands, thus achieving ultra-high data rates. However, the inhe…
Statistics Approximation-Enabled Distributed Beamforming for Cell-Free Massive MIMO
Zhe Wang, Emil Björnson, Jiayi Zhang +3
We study a distributed beamforming approach for cell-free massive multiple-input multiple-output networks, referred to as Global Statistics & Local Instantaneous information-based…
Impact of Antenna Arrays Misalignment on the Near Field Distance in Terahertz Communications
Peng Zhang, Vitaly Petrov, Emil Björnson
The extremely short wavelength of terahertz (THz) communications leads to an extended radiative near-field region, in which some canonical far-field assumptions fail. Existing near…
