Performance Analysis of Optical Wireless System with Aperture Averaging
Keywords:
-Abstract
The performance of FSO communication is degraded due to the turbulent atmospheric channel, causing variations
in intensity of the received signal at the receiver. In this paper the effect of aperture averaging is investigated on the BER
performance in a weak turbulent regime for coherent detection modulation schemes, namely ASK, FSK and PSK using lens of
different aperture diameters.
