摘要：
The laser pulse broadening and delay caused by cloud and aerosol can degrade the data transmission rate. The pulse broadening and the time delay induced by atmosphere channel are analyzed. Then the corresponding performance of communication rate for DSOC system which based on PPM scheme are investigated.In this paper, both the pulse broadening caused by cloud, aerosol and atmospheric turbulence and the time delay induced by turbulence are analyzed. Then the corresponding performance of communication rate for DSOC system which based on PPM scheme are investigated. Numerical results indicate that the cloud physical thickness and aerosol particle optical thickness can affect the communication rate severely. But, the rate can be improved by choosing lower modulation order and initial pulse width under clear atmosphere condition. The results enable us to determine suitable parameters in practical applications for better communication rate.
