| Popis: |
The multiphase screen numerical simulation method is used to simulate the fading variation caused by atmospheric turbulence in the laser communication link. Based on the traditional chase Hybrid Automatic Repeat Request scheme, the improved anti-fading scheme is studied. The simulation results show that the improved scheme combining multiframe interleaving and traditional HARQ anti-fading scheme can effectively avoid a series of errors and cause deep fading problems, and reduce the average bit error rate of the system compared to the long interleaving scheme. Comparing the traditional chase-type HARQ scheme also reduces the average bit error rate of the system and improves the throughput of the system. |
