WebbIn this work, we describe the implementation of a free space optical coherent communication system using QPSK modulation and heterodyne downconvertion that uses adaptive optics techniques and digital signal processing to mitigate turbulenceinduced phase fluctuations and channel impairments in coherent receivers. In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time inte…

Simulation implementation of the system is presented in Section 3. In section 4, the simulation results are presented and discussed. WebbLet us evaluate the average bit error rate (BER) of this system using a low complex but accurate method. Note that the BER depends on random fading, and it is a nonlinear function of the SNR. The nature of the nonlinearity is a function of the modulation/detection scheme employed [ 13 ].
