Abstract: A method includes receiving a first data packet on a first polarization portion of an optical signal from a second communication terminal through a free space optical link during a first time period and receiving a first data packet replica on the first polarization portion of the optical signal during a second time period. The second time period is delayed in time relative to the first time period. The method also includes determining receiving powers for the optical link during both the first time period and the second time period based on at least one of the received first data packet and the received first data packet replica. The method also includes selecting the one of the first data packet or the first data packet replica that is associated with the highest receiving power for the optical link as surviving data for maintaining the optical link.

Abstract: A method includes receiving a first optical signal at a first communication terminal from a second communication terminal through a free space optical link and determining a receiving power for the optical link based on the first optical signal. The method further includes adjusting an output amplification at the first communication terminal based on the receiving power for the optical link. The output amplification is adjusted to provide a second optical signal with a minimum transmission power for maintaining the optical link. The method transmits the second optical signal from the first communication terminal to the second communication terminal through the optical link.
