Abstract

In the atmospheric optical channel amplitude modulated beam experience slow amplitude variations coming from refraction caused by atmospheric turbulence. The receiver introduces noise making the detection of the binary data subject to errors. Normally physical-layer proactive error protection is used to protect the system. Physical-layer communication is naturally a connection-orientated service because a synchronization of the code-symbols is necessary. Because of fading it is demanding to keep synchronization anytime and continuously alive. Therefore additional effort for synchronization has to be made in order to overcome fading. In this paper a multi-layer proactive error protection scheme is introduced and discussed. In this multi-layer approach each level of protection is addressing different problems.
