Research Abstract |
For a new laser satellite communication which enables a higher capacity communication, we proposed a Markov-based channel model of satellite-to-ground laser downlink based on measurement results. Using this model, we also proposed a hard-decision channel coding scheme achieving a high error correcting ability with moderate decoding complexity. In addition to that, this channel code is enhanced to a one-way multi-rate channel coding scheme in which multiple pairs of coding rate and error correcting capability can be switched without any feedback links. Finally, we have supported the channel code design on small optical transponder (SOTA) developed by National Institute of Information and Communications Technology, Japan in Space Optical Communications Research Advanced Technology Satellite (SOCRATES) whose launch is planned in 2014.
