摘要：
Pointing error in wireless optical communication system has an impact on the geometric attenuation of the received optical power, resulting in a decrease in the received optical power of the system and affecting the performance of the system. In order to accurately analyze the effect of pointing error on the performance of wireless optical communication system, based on the intensity distribution of Gaussian beam, the accurate analytical solution of the geometric attenuation model of received optical power in wireless optical communication system with circular aperture is derived. The influence of pointing error on the geometric attenuation of the system under different parameters is simulated, and the accuracy of the analytical solution is verified and compared with the existing model. The results show that there are errors in using the existing approximate model to calculate the geometric attenuation, and the existing errors cannot be ignored, therefore the model derivation under the circular aperture is more in line with the actual situation. In the point-to-point communication and networking communication of wireless optical communication, it is more accurate to use the Gaussian beam geometric attenuation analytical model under pointing error. © 2021, Chinese Institute of Electronics.
