BER analysis of IM/DD FSO system with APD receiver over gamma-gamma turbulence
In this paper, the bit-error rate (BER) performance of intensity modulated with direct detection (IM/DD) free space optical (FSO) system using the on-off keying (OOK) and avalanche photodiode (APD) receiver is analyzed. The intensity fluctuations of the received optical signal are modeled b...

| Summary: | In this paper, the bit-error rate (BER) performance of intensity modulated
with direct detection (IM/DD) free space optical (FSO) system using the
on-off keying (OOK) and avalanche photodiode (APD) receiver is analyzed. The
intensity fluctuations of the received optical signal are modeled by gamma
gamma distribution, while both zero and nonzero inner scale models are
observed. The total receiver noise includes APD shot noise and thermal noise.
The BER expression is theoretically derived and numerical results are
presented. The results illustrate the BER dependence on the turbulence
strength, propagation path length, APD gain and noise temperature. [Projekat
