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
