Nonlinear Quasi-Synchronous Multi User Chirp Spread Spectrum Signaling
Nozhan Hosseini, David W. Matolak
Multi user orthogonal chirp spread spectrum (OCSS) can improve the spectral inefficiency of chirp spread spectrum (CSS) but is only feasible with perfect synchronism and without an…
Chirp Spread Spectrum Signaling for Future Air-Ground Communications
Nozhan Hosseini, David W. Matolak
In this paper, we investigate the use of chirp spread spectrum signaling over air-ground channels. This includes evaluation of not only the traditional linear chirp, but also of a…
Indoor and Outdoor Penetration Loss Measurements at 73 and 81 GHz
Mahfuza Khatun, Changyu Guo, David Matolak +1
In this paper, we present millimeter-wave (mmWave) penetration loss measurements and analysis at E-bands-73 GHz and 81 GHz. Penetration loss was measured for common building materi…
Millimeter-Wave Path Loss at 73 GHz in Indoor and Outdoor Airport Environments
Mahfuza Khatun, Changyu Guo, Letizia Moro +2
In this paper, two large-scale fading path loss models are presented based on indoor and outdoor channel measurements at 73 GHz. The line-of-sight millimeter-wave propagation measu…
Ultra-Wideband Air-to-Ground Propagation Channel Characterization in an Open Area
Wahab Ali Gulzar Khawaja, Ozgur Ozdemir, Fatih Erden +2
This paper studies the air-to-ground (AG) ultra-wideband (UWB) propagation channel through measurements between 3.1 GHz to 4.8 GHz using unmanned-aerial-vehicles (UAVs). Different…
