Performance of channel coding on free space optical (FSO) communication link

, 2020
The average loss power and the channel fading are among the major challenges of the free-space optical (FSO) communications through the turbulent atmosphere, resulting in the bit-error-rate (BER) performance degradation, or even communication link outage. For the same average received optical signal power, the degradation in BER performance is strongly
