In the atmosphere, the channel characteristics of the laser communication system will be influenced by the atmospheric attenuation and turbulence, which restricts the transmiss ion performance of the laser communication information; to scientifically design the laser communication link and improve the reliability of laser communication, based on the principle of laser communication, this paper gives the laser communication model under different atmospheric conditions, analyzes the atmospheric channel characteristics of laser communication system under the conditions without turbulence and with turbulence; derives the mean values and variances of output voltage under corresponding channels, according to the definition of bit error rate (BER) in laser communication system, establishes the BER calculation model of laser communication system under various atmosphere conditions and discusses the effects of different correlation factors on the system BER. Through the calculation and analysis, it can be shown that the BER of the laser communication system decreases with increasing the threshold voltage and the power of laser , when the intensity of laser probability tends to normal distribu tion, the system BER will remain constant and the reliability of data transmission will achieve the optimal value..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
