| Abstract(in English) | In satellite laser communications, a long round-trip delay occurs due to the long distance of the satellite altitude from earth ground. To achieve an multi-rate transmission in such a long delay satellite link, we propose a multi-rate low density generator matrix (LDGM) code for satellite laser communications. Since the proposed scheme does not utilize a preamble transmission of the rate information nor the repeat request scheme, a long feedback delay in the satellite link and a decrease of transmission efficiency can be avoided. This scheme enables the tradeoff with the quality and the rate-efficiency of transmission from the transmitter-side state. In the receiver, an exact rate-decision and decoding are conducted without the preamble. It is shown through computer simulations that the proposed scheme is effective in the satellite-to-ground optical link. |
