RZ-DPSK Optical Modulation For free Space Optical Communication Satellites

Abstract : We demonstrate up to 4 dB improvement in optical receiver sensitivity using Return-to-Zero Differential Phase Shift Keying (RZ-DPSK) modulation compared with Non-Return-to-Zero On Off Keying (NRZ-OOK) in free space optical communication from satellite to ground at 40 Gbit/s data rate. This has been assessed using simulation software. An experiment is taking place to validate this result for 10 Gbit/s.
