Title of the Talk: Jamming in Free Space Optics

Abtract of Talk:In recent years, free space optical (FSO) communication has emerged to imprint its valuable contribution in high-speed wireless communication society due to its manifold advantages. FSO systems have immense potential for providing high-data-rate communication link and can be easily deployed over wide ranges of applications (also gained utmost attention in 6G and IoT platforms). However, reliable communication cannot be assured in security-constrained protocol-based FSO applications (especially in military platforms) due to technical constraints imposed on FSO system design and deployment (like high field-of-view, confined optical wavelengths). Under such technical circumstances, the FSO system may become vulnerable as it can be hampered by intentional or unintentional jammer that cannot be easily avoided by the legitimate sources. So, it becomes crucial to investigate different protocol based FSO systems to explore the performance statistics in presence of detrimental jamming activity and also to develop communication strategies to alleviate the impact of jamming during the data transmission between the authorized users.
