    Performance Analysis of Relay-Assisted Free-Space Optical Communication (FSO) Under Gamma-Gamma Atmospheric Turbulence Channels with Pointing Errors
    (Springer Science and Business Media Deutschland GmbH, 2023) Tarimo, C.P.; Kulkarni, M.
    The use of infrared and visible spectrum parts in the electromagnetic spectrum has made great changes in communication because of its higher data rate, high security, and larger bandwidth. This technology can be implemented using guided media; that is optic fiber cable or unguided media such as free-space optical communication (FSO). In this work, gamma-gamma distribution with relay-assisted transmission as the main fading mitigation tool for FSO systems under different atmospheric conditions is proposed. The performance was evaluated by considering signal-to-noise ratio (SNR) and BER for a link with different atmospheric conditions using amplify and forward method for the relay transmission, in which geometrical losses and pointing errors were considered. Further, the output power versus distance was analyzed using multiple-input multiple-output (MIMO) technology. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
