  • This paper investigates the performance of a new generalized frequency division multiplexing (GFDM) parallel relay free space optical (FSO) communication system using multi-input multi-output (MIMO) orthogonal space-time block codes (OSTBC) scheme. Under the M distribution atmospheric turbulence, taking into account the triple effects of irradiance, pointing errors and path loss, the mathematical expression of system symbol error rate is derived with the help of Meijer G-function. The symbol error performance of GFDM is compared with on-off keying, Gaussian minimum shift keying, polarization shift keying and orthogonal frequency division multiplexing (OFDM) modulation methods. The effects of the MIMO-OSTBC parallel relay scheme on the GFDM system including filter roll down coefficient, the number of transmitting and receiving antennas, the number of relays, normalized beamwidth and jitter variance are analyzed, and the numerical results are verified by Monte Carlo simulation. This work provides a good foundation for engineering applications.
