Abstract
Theoretical analysis as well as system simulation of a NRZ/RZ (NRZ and duty cycle 33% 50% 66% RZ) shaped APPM (2×4 and 4×4) modulated scheme for gamma-gamma distribution turbulent free-space optical communication is done. Results show lower BER in RZ scheme especially with duty cycle 33%, however the NRZ scheme has higher frequency efficiency. So both BER performance and frequency efficiency can be synthetically considered to choose a proper scheme according to simulation results.
