Bit Error Rate Performance for Modulating Retro-Reflector Free Space Optical Communication System Based on Adaptive Threshold under Atmospheric Turbulence
Evaluation for decision threshold corresponding to the minimum bit error rate(BER)of modulating retroreflector(MRR)free space optical communication(FSOC)system is presented.And based on this threshold,the closed form expression of the BER for MRR FSOC system is obtained,considering the effects of adaptive threshold noise and photodetector noise.According to the derived expressions,the effects of adaptive decision threshold parameters and modulation extinction ratio on BER are analyzed.Results show that the ...
