This paper presents 73 GHz wideband outdoor foliage and ground reflection measurements. Propagation measurements were made with a 400 Megachips-per-second sliding correlator channel sounder, rotatable 27 dBi (7° half-power beamwidth) horn antennas at both the transmitter receiver, to study foliage-induced scattering de-polarization effects, assist in developing future wireless systems that will use adaptive array antennas. Signal attenuation through was measured be 0.4 dB/m for co-...
This paper presents large-scale path loss models based on extensive ultra-wideband millimeter-wave propagation measurements performed at 28 GHz and 73 in three typical indoor office layouts - namely: corridor, open-plan, closed-plan. A previous study combined all together, while this separates them for site-specific model analysis. Measurements were conducted using a 400 megachips-per-second broadband sliding correlator channel sounder with 800 MHz first null-to-null RF bandwidth 48...
Natural sea waves are typically multi-directional. However, the existing studies on interaction of and structures mostly concentrate uni-directional waves. In this study, using a higher-order boundary element method based nonlinear potential flow theory perturbation expansion technique, numerical model is developed to investigate hydrodynamic performance semi-submersible wind turbine foundation in uni- multi-directional Comprehensive validations with wave-tank experiment conducted. It found...
As the siting of wind turbines increasingly transitions from shallow water to offshore deep-water locations, improving platform stability floating is becoming a growing concern. By coupling porous shell commonly used in traditional marine structures, with FOWT (floating turbine platform), new spar-buoy was designed. A numerical model investigating effect aero-hydro-mooring system developed, and results motion response are compared OC3-Hywind spar. The two platforms simulated time-domain...
Monopiles are commonly utilized in offshore wind farms but prone to non-linear wave loads and run-ups, significantly affecting their engineering design. Therefore, it is crucial pursue a complete understanding of the action on monopile foundations. Both numerical experimental investigations run-ups an turbine foundation performed this paper. The experiment carried out at scale 1/30 flume State Key Laboratory Coastal Offshore Engineering, Dalian University Technology, which along measured....
This paper presents 73 GHz human blockage measurements for a point-to-point link with 5 m transmitter-receiver separation distance in an indoor environment, that walked at speed of approximately 1 m/s perpendicular orientation to the line between transmitter and receiver, various distances them. The experiment measures shadowing effect moving body when using directional antennas receiver millimeter-wave radio communications. were conducted 500 Megachips-per-second wideband correlator channel...
