In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our emulator is in the form of an atmospheric chamber with dimensions ...
On the effects of temperature on the performances of FSO transmission under qatar's climate
(IEEE, 2017-11-14)
Strong atmospheric turbulence can highly affect the free space optical (FSO) link. In fact, the strength of turbulence is depending on weather factors where the temperature is considered as the main parameter increasing ...
Performance of multicarrier cooperative communication systems over underwater acoustic channels
(IET Communications, 2017)
Multicarrier transmission in the form of orthogonal frequency division multiplexing (OFDM) is an efficient method to handle inter-symbol interference resulting from the frequency selectivity of the underwater acoustic (UWA) ...
