    Sammanfattning : Optical free space communication system faces the major challenge because of the atmospheric condition. Signals receive in the ground station using two different types of receivers (Coherent detection and Intensity Modulation and Direct Detection (IM/DD)). LÄS MER

  5. 4. Routing in Terrestrial Free Space Optical Ad-Hoc Networks

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Författare :Yao Dong; Mohammad Sadegh Aminian; [2014]
    Nyckelord :Free Space Optical Ad hoc networks; routing; FSO; ITS;

    Sammanfattning : Terrestrial free-space optical (FSO) communication uses visible or infrared wavelengths to broadcast high speed data wirelessly through the atmospheric channel. The performance of terrestrial FSO channel mainly depends on the local atmospheric conditions. LÄS MER

  7. 5. Design and implementation of 1GbpsLaser Ethernet Transceiver (LET) for Free-Space Optical communications

    Uppsats för yrkesexamina på avancerad nivå, KTH/Rymd- och plasmafysik

    Författare :JORGE PACHECO LABRADOR; [2014]
    Nyckelord :;

    Sammanfattning : Free Space Optical (FSO) communications are an emerging technology. Multiple resources around the world are being dedicated to the study and implementation of associated technologies. The possibility of high data rates, lower masses and more power efficient antennas are the expected advantages of these systems. LÄS MER
