- W2950829947 abstract "In satellite-to-ground laser communication, atmospheric turbulence will seriously deteriorate the system performance. The DPSK modulation technology is usually used to control the influence of atmospheric turbulence. The Meijer G-function is used to give the closed-form expression of the average bit error rate (ABER) of the system considering the combined influence of the atmospheric turbulence and the pointing errors, where the atmospheric turbulence channel is submitted to the Gamma-Gamma distribution and the pointing errors is submitted to the Beckman distribution. Through numerical simulation, the influence of system transmitting power, normalized beam width and zenith angle on the BER performance of the system is analyzed. The simulation results show that the ABER of the system decreases with the increase of the transmitting power, the error performance of the system considered the bias errors is obviously higher, and the error performance is also different when the azimuth and elevation normalized jitter deviation are not equal. The system performance will decline rapidly with the increase of the zenith angle. The BER of the system decrease firstly and then increase with the increase of the normalized beam width, and the optimal normalized beam width can be found to achieve the best performance." @default.
