Abstract
Bit error rate (BER) performance of the free space optical communication (FSOC) systems using differential signaling over partially correlated atmospheric turbulence fading with and without partially correlated pointing errors is investigated. In order to do the BER performance analyses, we first derive a useful mathematical expression for the joint probability density function of the system under combined effects of the partially correlated atmospheric turbulence fading and partially correlated pointing errors. Then based on this obtained result, two mathematical BER expressions of the system affected by either the partially correlated atmospheric turbulence or both the partially correlated atmospheric turbulence fading and the partially correlated pointing errors are obtained. The accuracy of the derived BER expressions is demonstrated by the Monte Carlo simulations, and the effects of the system parameters on the BER performance are studied. From the simulations, we present some important and interesting analytical results of the BER performance with the system parameters.
