Simulation of free-space communication using the Orbital Angular Momentum of radio waves

2014 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2014
The Orbital Angular Momentum (OAM) property of radio waves can be efficiently used to combine multiple free-space radio-communication channels into a single carrier frequency. This paper presents a study of such a multichannel system using Simulink model of radio-waves with different OAM value combined together.

Measured inhouse radio wave propagation characteristics for wideband communication systems

8th European Conference on Electrotechnics, Conference Proceedings on Area Communication, 2003
The frequency-selective radio-wave propagation characteristics for in-house communication systems are statistically characterized for the cases of line-of-sight and obstructed path propagation. Using the theory of random time-variant linear filters, it is found that the RMS (root mean square) delay spread, the Doppler spread and coherence time, the ...

EXPLORATION OF EMISSION OF RADIO WAVES FOR MEANS OF COMMUNICATION AND CONTROL OF UNMANNED AERIAL VEHICLES

2023
В статті досліджено поширення радіохвиль в реальних умовах для тропосферної і земної хвиль в залежності від напряму, стану середовища, відстані та потужності випромінювача для вирішення задач перехоплення бпла. Знайдено найбільш раціональні способи розрахунку поширення радіохвиль.
