Abstract

In this paper, the system performance of free space optical communication of coherent OFDM is studied by the K distribution atmospheric turbulence model under strong turbulent conditions. The channel attenuation model derives the closed form expressions of the outage probability and symbol error rate of the system under the three factors of atmospheric turbulence, path loss and pointing error. The signal mapping method has used QAM. Simulation respectively analyzes the single jump, triple jump and four system mapping, the subcarrier number on order coherent OFDM the interruption of FSO system performance and the influence of the error performance came to the conclusion that the simulation provides a reliable theoretical basis for practical applications.
