Abstract

Abstract:

Aiming at the uplink of laser communication between airplane and satellite,the factors including the ambient light,the loss of laser propagating in atmosphere,the receiving efficiency of receiver and the laser intensity fluctuation,which all can affect the link performance,were theoretically modeled and analyzed.On the basis of the modeling and analyzing,a link bit error rate (BER) model was proposed by considering on-off-keying (OOK) modulation and direct-detection combined with the Webb-Gaussian approximation of avalanche photodiode detector (APD).A numerical simulation was performed and the relationship between BER and signal laser power incident on APD was got.It shows that BER decreases while the laser power increases and an approximately log-linear relationship between decreasing speed of BER and laser power can be obtained.Finally,the minimal transmitting power,0.873W,at transmitter was computed as link could achieve 10^-7BER.

Key words: laser communication, link, bit error rate, power analysis, satellite
