Abstract.  A transmission scheme is proposed which loads differential phase shift keying (DPSK) information and circular polarization shift keying (CPolSK) information on the same optical carrier for free space optical links through an atmospheric turbulent channel. Theoretical models of modulation and demodulation are derived and a design is specified to detect and recover the information with two mutually independent branches in order to meet the requirement for a high real-time transmission capacity and to entirely remove modulation-induced cross talk. Simulation results show that the CPolSK/DPSK system has a high tolerance to intensity scintillation and phase noise caused by atmospheric turbulence. A bit error rate performance comparison of a CPolSK system, a DPSK system, and a CPolSK/DPSK system is also presented to comprehensively demonstrate that the CPolSK/DPSK system outperforms the other two modulation techniques in terms of a high real-time transmission capacity.
