This paper investigates the shadowing effect induced by an aircraft during maneuvering for air-to-ground communication at C band. Narrowband measurements with a linear flight route and a circular flight route have been conducted and the results are compared in this paper. It is found that, the ...
However, when considering the effect of shadowing on the interior of the building, it is shown that effective spectrum availability decreases.Washington MedinaFrancisco NovilloEduardo ChancayJuan Romero-Arguello会议论文
The system has a specific delay profile different from the infrared wireless communication. In this paper, we discuss the shadowing effect on the system utilizing plural LED lightings including the performance of ISI based on the delay profile. We consider the downlink transmission based on TDMA ...
The function to implement log-normal shadowing is given above and the test code is given next. Figure 1 above shows the received signal power when there is no shadowing effect and the case when shadowing exists. The results are generated for an environment with PLEn = 2, frequency of transmi...
and they applied the DoE method by comparing the measured values with the model calculated values in order to depart shadow alarms [7]. The HDKR/S (Hay, Davies, Klucher, Reindl/shadow) model was modified by S. Yadav et al. to take into account the effect of shadowing to evaluate the...
We study the effect of radio signal shadowing dynamics, caused by vehicles and by buildings, on the performance of beaconing protocols in Inter-Vehicular Communication (IVC). Recent research indicates that beaconing, i.e., one hop message broadcast, shows excellent characteristics and can ...
The presence of obstacles in the propagation path is a critical factor in air-to-ground (AG) communication. The behavior of wireless signal propagation depends on several variables, such as frequency, building height, elevation angle, and street design. This paper aims to ...
And the system has specific wireless channel impulse response differing from infrared wireless communication. In this paper, we discuss about shadowing effect on the system utilizing plural LED lightings including the performance of ISI based on the impulse response. We consider the downlink transmission...
ShadowingAd-hocWireless home linkOFDMWe propose ad-hoc node repeater in Wireless Home Link (WHL) to mitigate the effect of shadowing caused by human bodies or other obstacles. In this system, when a WHL node is not doing any communication, it plays a role of a repeater retransmitting the ...
