摘要 | Coherent free-space optical communication with 8-quadrature amplitude modulation (8-QAM) using joint algorithm of amplitude compensation and digital phase recovery is proposed. Compared with traditional free-space optical communication schemes, the scheme we proposed not only can restore the signal without requiring the knowledge of instantaneous channel state information, but also has higher spectral efficiency. Numerical studies show that the bit error rate of the proposed system is four orders of magnitude lower than that of the 8-QAM system without joint algorithm, when the frequency offset f0=20 MHz between the receiver and the transmitter, the lasers joint linewidth f=10 kHz, and the signal-to-noise ratio is 20 dB for a lognormal turbulence channel with =0.25 and phase noise with 2=0.07. 2020, Science Press.
