Abstract
Free Space Optics (FSO) link exploits the tremendous network capacity and is capable of offering wireless communications similar to communications through optical fibres. However, FSO link is extremely weather dependent and the major effect on FSO links is due to adverse weather conditions like fog and snow. In this paper, an FSO link is designed using an array of receivers. The disparity of the link for very high attenuation conditions due to fog and snow is analysed using aperture averaging technique. Further effect of aperture averaging technique is investigated by comparing the systems using aperture averaging technique with systems not using aperture averaging technique. The performance of proposed model of FSO link has been evaluated in terms of Q factor, bit error rate (BER) and eye diagram.
4 Conclusions
This paper targets the alleviation of the effects of adverse weather conditions on free space communication link using aperture averaging technique. The link using array of receivers without aperture averaging technique is good for moderate weather conditions. But the link does not provide optimum performance in adverse weather conditions. It has been observed that the simulated link with high laser power is providing optimum performance even in adverse weather having attenuation levels up to 128 dB/km. Further, a comparison is provided among the system using aperture averaging technique and system not using aperture averaging technique. The results reveal the large variation in the output results. It is thus concluded that with the application of aperture averaging technique in the link, the performance of link using array of receivers can further be improved, thus enhancing the range, accuracy and efficiency of the link.
