The effect of the atmospheric turbulence on the bit error rate in a laser communication system with multiple beam transmission and reception was analyzed.Ignoring other noises in the system, atmosphere turbulence was the only cause for bit error rate.After solving the equation of laser transmission in atmospheric turbulence field, the relation between the system bit error rate,transmission range and space of atmospheric channels was obtained under the condition of the different number of transmitting antenna and correlation coefficients.The result indicated; under the weak fluctuation condition, the system bit error rate reduces quickly while increasing the number of transmitting antenna or decreasing the correlation coefficient or increasing the space between atmospheric channels; the system bit error rate increases while the turbulence intensity enhances; the system bit error rate reduces while the wavelength of transmission laser increases.When the transmitting antenna number is definite, system bit error rate will reduce with the space of atmospheric channels increasing.
