Performance evaluation of a novel relay assisted hybrid FSO / RF communication system with receive diversity
Mohammad Ali Amirabadi
One of the main problems in mobile communication systems is the degradation of Radio Frequency (RF) connection when mobile user is far from base station. One way to solve this prob…
A new optimization problem in FSO communication system
Mohammad Ali Amirabadi, Vahid Tabataba Vakili
According to the physical phenomena of atmospheric channels and wave propagation, performance of wireless communication systems can be optimized by simply adjusting its parameters.…
A novel hybrid FSO / RF communication system with receive diversity
Mohammad Ali Amirabadi
In mobile communication system, due to the limitations of mobile device such as low power supply as well as small size, most of the processing should be done at the Base Station. U…
