Pulse position modulation coding schemes for optical intersatellite links

By Fadi Ghosna and Martin J.N. Sibley


The rapid and significant development of communications links between satellites has made it possible to use various applications such as relay voice, video, multimedia, etc. As a result,\ud a great deal of research has been done in this field during the last few years to reduce power consumption and increase transmission reliability.\ud \ud \ud This research project work is concerned with intersatellite links in free space, with optical links\ud using laser sources being considered in particular. This paper discusses the use of several different coding schemes for use in such links: digital pulse position modulation (DPPM); multiple pulse position modulation (MPPM); Dicode pulse position modulation (Dicode PPM). A comparison is made using error rate performance and coding efficiency
