Summary: | In this paper, the quality of the Polarization Shift Keying (PolSK) modulated
signal in a Free Space Optical (FSO) system is analyzed. The atmospheric
channel is statistically modeled with four different distributions, namely,
the Gamma-Gamma distribution, Negative Exponential distribution,
Kdistribution, and I-K distribution. For all four channel models, the
Average Bit Error Rate (ABER) at the receiving side of the system is
determined in an analytically closed form. The results are graphically
presented and discussed in order to determine the impact of certain
parameters on the ABER, i.e., the quality of the received signal in the
PolSK modulated FSO system. These parameters are the Signal-to-Noise Ratio
(SNR), the FSO link distance, the wavelength at which the signal is
transmitted, and the atmospheric turbulence strength.
