Bit Error Rate Performance of Hybrid Modulated Faster-Than-Nyquist Atmospheric Optical Communications Under Gamma-Gamma Channel
Pulse-position modulation (PPM) has the advantages of simplicity and high interference immunity but is affected by the issues concerning low frequency band utilization. To improve the system’s bandwidth utilization and data transmission rate, a hybrid modulated faster-than-Nyquist (PSK-PPM-FTN) rate atmospheric optical communication scheme in combination with phase-shift keying (PSK) and PPM is proposed in this paper. The bit error rate (BER) is derived over Gamma-Gamma-distributed atmospheric channel. In addition, the relationship of BER and transmission distance, laser wavelength, and time acceleration factor
