摘要：
In this paper, we derived the average bit error rate (BER) in closed-form expression of free space optical (FSO) homodyne systems over atmospheric turbulence channels with Gamma-Gamma distribution. For derivation of the closed-form expression we used special integral and transformation of the Meijer G function. Additionally, we numerically analyzed the average BER behavior according to the average SNR and different turbulence strengths considering several modulation methods including phase shift keying (PSK), amplitude shift keying (ASK), and frequency shift keying (FSK).
