摘要：

A numerical calculating model is proposed for characteriz-ing the BER performance of the detector working among the 2-D asymmetric distorted spot on the effects of atmo-spheric turbulence under weak turbulent conditions. Based on the isotropy of the beam wander effect, we introduce a beam wander vector to describe the behavior of the detector drifting among the receiving plane. Furthermore, using the cake-cutting method, the overall PDF of the light intensity is approximated by the average PDF of light intensity inter-cepted by the detector drifting in all different directions. The results demonstrate that the model obtains the overall PDF of the light intensity received by the detector and ana-lyzes the BER performance of the communication system efficiently. Being an extension of the traditional 1-D calcu-lation, our proposed model has important implications for designing the space uplink optical communication system. (c) 2023 Optica Publishing Group
