Specifically, the closed-form expressions of outage probability and average bit error rate(ABER) are derived with Meijer-G function and further confirmed by Monte Carlo(MC) simulation. Subsequently, the outage performances of this system are analyzed in detail with the influence of PE, turbulence strengths, structure parameters and weather conditions for plane and spherical waves. Moreover, cyclic coding is used in this work to further optimize system performance.展开更多
