On the Performance of a Relay-Assisted Multi-Hop Asymmetric FSO/RF Communication System over Negative Exponential atmospheric turbulence with the effect of pointing error
Mohammad Ali Amirabadi
In this paper, a multi-user multi-hop hybrid FSO / RF system is presented. This structure is consisted of two main parts. The main motivation of presenting this structure is commun…
New expressions on the performance of a novel multi-hop relay-assisted hybrid FSO / RF communication system with receive diversity
Mohammad Ali Amirabadi
In this paper a novel multi-hop relay-assisted hybrid Free Space Optical / Radio Frequency (FSO / RF) communication system is presented, in which a mobile user is connected to the…
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…
New expression on the performance of a novel multi-hop relay-assisted hybrid FSO / RF communication system
Mohammad Ali Amirabadi
In this paper a novel multi-hop relay-assisted hybrid FSO / RF system is presented. It is assumed that direct RF connection between mobile users and source Base Station is impossib…
Performance of a Relay-Assisted Hybrid FSO/RF Communication System
Mohammad Ali Amirabadi
This paper investigates performance of a relay assisted hybrid Free Space Optical / Radio Frequency (FSO/RF) communication system. The proposed structure is particularly recommende…
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…
Performance Comparison of two novel Relay-Assisted Hybrid FSO / RF Communication Systems
Mohammad Ali Amirabadi
In this manuscript, two novel multi-hop relay-assisted hybrid Free Space Optical / Radio Frequency (FSO / RF) communication systems are presented and compared. In these structures,…
