Impact of receiving aperture on BER performance of optical wireless communication systems
Receiving aperture can effectively improve the BER performance of optical wireless communication links.Starting with the averaging effect of apertures
this paper compares the averaging factor differences between annular apertures and circular apertures and analyzes their impacts on the system BER.The simulation results reveal that
when receiving aperture diameter D<8 cm
there are fairly great differences between the averaging factors of the two shapes of apertures and the relative errors of the BER are fairly large.However
when D≥8 cm
their averaging factors are basically identical and the relative errors are little or negligible.
