| Abstract(in English) | In satellite laser communications, fluctuations of received optical power induced by atmospheric scintillation cause transmission burst errors. To tackle this problem, we previously proposed an application of polar codes for the error correction, and showed the improved performance in the experimental results of long-distance terrestrial free space optical (FSO) transmission. However, there still existed a residual burst error due to strong atmospheric fluctuations and the quality of transmission deteriorated. Therefore, in this study, we propose a channel estimation and equalization scheme for FSO polar-code transmission to improve the performance. Through experimental results, we show that the error rate performance of the proposed scheme improves, and the polar code transmission in FSO channel is effective. |
