Asymptotic Performance Analysis of Two-Way Relaying FSO Networks With Nonzero Boresight Pointing Errors Over Double-Generalized Gamma Fading Channels

In this correspondence, an asymptotic performance analysis for two-way relaying free-space optical (FSO) communication systems with nonzero boresight pointing errors over double-generalized Gamma fading channels is presented. Assuming amplify-and-forward relaying, two nodes having the FSO ability can communicate with each other through the optical links. With this setup, we derive some asymptotic analytical results for the outage probability and average bit error rate. Furthermore, we provide an asymptotic average capacity analysis for high signal-to-noise ratio by using the moments-based method.
