Free space optical systems can transmit at high data rates and can provide cheap, easily deployable solutions for both short-term and long-term communication needs. Controlling the direction of energy propagation from the optical transmitter can prevent communication between two users from interfering with another user in an optical network and can reduce the susceptibility of the system to eavesdropping...
Free space optical communication through the atmosphere has the potential to provide secure, low-cost, rapidly deployable, dynamic, data transmission at very high rates. Despite the ability for free space optical technology to transmit a narrow beam of light to a specific destination, it is still possible for an eavesdropper to gather light and decode information intended for another user. This paper...
In recent results, a theoretical framework has been developed that shows that wavefront predistortion with transmitter channel state information can effectively mitigate turbulence induced fading for free space communication systems. The theoretical framework, however, relies on the assumption of perfect channel state information available at the transmitter, which is not physically realizable since...
