Abstract :
A free-space optical communication system using subcarrier binary phase-shift keying modulation is analyzed for Gamma-Gamma turbulence channels with pointing errors. We study the bit-error rate performance of such system and obtain highly accurate bit-error rate approximations using a series expansion approach. Asymptotic error rate analysis is also presented. Our asymptotic analysis reveals some unique transmission characteristics of such system.
