Abstract

Error performance of a coherent free space optical system with K-distributed turbulence is studied. A closed-form expression of the moment generating function for K-distributed turbulence is derived, and the moment generating function is used to obtain the exact error rates for binary phase shift keying (BPSK), BPSK with spatial diversity, as well as differential phase-shift keying. Based on our analytical moment generating function expression, asymptotic error rates in large signal-to-noise ratio regions are obtained.
