Abstract :
An analytical approach is presented to evaluate the bit error rate (BER) performance of an optical free space link considering the effect of pointing error. The analysis is presented to evaluate the BER with multiple photo detectors in the presence of pointing error. The results are evaluated at a bit rate of 10 Gbps for various system parameters. The receiver sensitivity with pointing error is evaluated for SISO and SIMO FSO links for various system parameters. It is noticed that SIMO FSO links can tolerate more pointing error compared to SISO.
