Multipath characteristics of impulse radio channels
VTC2000-Spring. 2000 IEEE 51st Vehicular Technology Conference Proceedings (Cat. No.00CH37026), 2002We investigate the multipath characteristics of the impulse radios (IR) which have drawn much attention for future high-speed wireless communication services. For this objective, we observe the characteristics of bit error rates through computer simulations for the deterministic two-path model and the statistical indoor multipath model of Saleh and ...

Impulse Signal Transmission and Synthesis Characteristics
2018 IEEE 3rd International Conference on Cloud Computing and Internet of Things (CCIOT), 2018Transmission and synthesis characteristics of impulse signals is one of key technologies of the time-domain radar system. This paper regards the unit antenna as the radiation power and gives transmission and synthesis characteristics of the array antenna impulse signals. From theoretical and experimental results, the experimental results are consistent

Impulse sparkover characteristics of sphere-rod gaps
IEE Proceedings - Science, Measurement and Technology, 2005The sparkover behaviour of sphere-rod gaps under standard impulse voltages is investigated by assessing the influence of gap spacing, impulse voltage waveshape and polarity, and atmospheric conditions on the distribution of the sparkover voltage. At sparkover the growth of streamers of both polarities can be estimated since a value of 2 MV/m is found ...

Thrust Bearing Characteristics in Impulsively Generated Motion
Journal of Lubrication Technology, 1977Numerical solution is obtained for the case where the fluid within the lubricating film is initially at rest, however, at time zero the infinitely long slider suddenly assumes a constant velocity. Subsequently, the velocity and pressure fields are generated yielding time dependent load capacity.

Ablation Impulse Characteristics by Laser Pulse Irradiation
47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009For the future space propulsion system, the laser propulsion is expected to be a useful method. The most prominent advantage of the laser propulsion is that the system can generate the impulse without carrying the power supply onboard. This propulsion system has the possibility to improve the payload ratio compared to the conventional chemical ...

Servo motor characteristics by impulse testing
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1962IT IS THE PURPOSE of this paper to suggest the possibility and to consider some of the initial analyses and results of determining certain servo motor steady-state and transient characteristics by impulse testing. If the method can be successfully applied to servo motors, it appears to be reasonable that many other servo and control components could be

Steep Impulse Voltage Characteristics of Suspension Insulators
Electrical Engineering in Japan, 1995AbstractTransmission and distribution lines are sometimes struck by lightning and there is some risk of electrical puncture of suspension insulators due to high and steep lightning surge voltage. When the insulators suffer from steep lightning surge voltages, the solid insulating body of the insulators sometimes is punctured before external flashover ...

Experimental investigation of grounding grid impulse characteristics
European Transactions on Electrical Power, 1998AbstractThe paper provides a procedure for experimental determination of the grounding grid impulse characteristics. The principles of forming the measuring scheme, disposition and characteristics of the equipment used are described. Some of the numerous experimental results for the square‐shaped grounding grid are presented.
