  • Data retransmission for atmospheric free space optical communication system
    Patent number: 10075233
    Abstract: Exemplary embodiments described a transmission scheme for use in a bi-directional Free Space Optical (FSO) communication system. Each node locally stores a transmitted data block until and acknowledgement is received that it was properly decoded. In the event that a decode was unsuccessful, the data is retransmitted. The receiving node may then add the received signals to then attempt a decode on a combined signal. The system may also include dynamic controls such that the retransmitted signal may be optimized to improve the probability of a successful decode.
    Type: Grant
