2.50 Gbit/s optical wireless communication system using PPM modulation schemes in HAP-to-satellite links

HAP-to-satellite, one of the important applications of FSO/OWC technology, which will be deployed in space in the near future. In this paper, we have presented analysis of 2.50 Gbit/s OWC system using PPM modulation schemes and a distance of 2500 km was achieved at BER 10−6 in HAP to satellite links.
