- W2979987492 abstract "Atmospheric turbulence is a major limiting factor in free-space optical communication systems, causing intensity flicker and phase fluctuations in the beam. In order to cope with the influence of atmospheric turbulence and background light on wireless laser communication, a wireless laser communication system was designed and implemented. The system used the digital fountain code Raptor10 code to improve the reliability and anti-interference ability of the communication system. In addition, the Barker code was used as the frame header and pulse position modulation(PPM) mode, and the data coding, modulation, frame synchronization, demodulation and decoding were completed with the field programmable gate array(FPGA) as the core. The emission source was a 532 nm laser and the detector used a single point APD from Silicon Sensor. Finally, the entire wireless laser communication system was tested in 2 km of free space, and the test results were stable and reliable." @default.
