| Abstract: | Optical satellite communications based on laser hnk has been drawing wider attention in light of the disparities between the disadvantages of RF links in traditional satellite communi- cations and the advantages in capacity, anti-interference and encryption of optical communica- tions. We give an introduction to the status quo of the researches in optical satellite communica- tions both home and abroad. We have made a study of the structure of optical satellite network in terms of inter-satellite laser links, channel coding and network and the key technologies. Routing algorithm of dynamic virtual topology and WDM wavelength assignment algorithm are proposed. |
