Paper Abstract

Surveillance using aerial systems provides a different angle of monitoring, maintain security or locate wanted targets. The imaging data is live streamed to the ground using different types of datalinks. However, the large amount of imagery and video information transferring from the unmanned aerial vehicle (UAV) require high data rate for communication. A method of optical wireless communication that has a high bandwidth which can be used in the field of UAV is free space optics (FSO). FSO technology offers faster and secure data transmission. In this work, FSO channel model have been investigated pertaining to atmospheric turbulence to analyze the average spectral efficiency (ASE) using various modulation schemes such as Polarization Shift and On-Off Keying, and Coherent Optical Wireless Communication. The atmospheric turbulence channel model depends on various parameters Such as the refractive index structure, strong or weak turbulences. Presented in this work, the refractive index is manipulated to obtain the exact turbulence differences through various operational altitudes while operating the UAV. Furthermore, the misalignment error between the overall system receiver and transmitter is considered when performing the analysis. The results show the performance of the optical link in different altitudes and different modulation schemes to optimize the performance of the link.
