Free Space Optical Communication: Challenges and Mitigation Techniques
In recent years, free space optical (FSO) communication has gained significant importance owing to its unique features: large bandwidth, license free spectrum, high data rate, easy and quick deployability, less power and low mass requirement. FSO communication uses optical carrier in the near infrared (IR) and visible band to establish either terrestrial links within the Earth’s atmosphere or i...
متن کاملIncremental adaptive networks implemented by free space optical (FSO) communication
The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...
متن کاملAnalyze and mitigation of Interference in Free space optical communication systems
Free space optical communication systems have special privileges in comparison with radio transceivers in last-mile connections. Some of These features are high security, low power consumption, extremely high bandwidth and low interference. The fact that the interference free systems are one of the nowadays challenges, as well as the stems and sources of interference were investigated in this r...
متن کاملClutter mitigation techniques for space-based radar
The mission of a ground moving target indication (GMTI) radar, as its name implies, is to detect and classify ground-based vehicles, even ones with very low velocities. This type of radar can provide a wide area of coverage and frequent updates of a specific area of interest if the radar is placed on a satellite with a low earth orbit. However, because of the large footprint of the radar on the...
متن کاملChromatic Dispersion Mitigation in Single Carrier High Speed Coherent Optical Communication Using Digital Signal Processing Techniques
Optical fiber networks have been emerged to be the backbone of global communication infrastructure in present world. But, they are currently experiencing an unprecedented level of stress in order to meet the demand of increasing bandwidth-hungry applications. Moreover signals are frequently subjected to distortion due to optical fiber impairments while being propagating through a fiber optic ca...
