英文摘要	Free-space coherent optical communication system using irradiance modulation(IM/CD) with dynamic detection threshold is proposed. Compared with traditional irradiance modulation and direct detection(IM/DD) systems, the system we proposed can detect the signal without requiring the knowledge of instantaneous channel state information(CSI) and the probability density function(pdf) of the turbulence model and achieve better average bit error rate(BER) just by only improving the LO power. Analytical expressions are derived for the average bit error rate of the system. Numerical studies show that the proposed system can achieve comparable performance to the idealized adaptive detection system, with a signal-to-noise ratio performance loss of only 1.4 dB at a BER of 10-9 for a lognormal turbulence channel with =0.25 and phase noise with =0.07 when the local oscillator(LO) amplitude and transmitting amplitude are assumed to be unity. 2019, Science Press.
