Abstract-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 (AF) relaying, two nodes having the FSO ability can communicate with each other through the optical links. With this setup, an approximate cumulative distribution function (CDF) expression for the overall signal-to-noise ratio (SNR) is presented. With this statistic distribution, 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 SNR by using the momentsbased method.Index Terms-Double-generalized gamma fading, free-space optical communication, pointing errors, two-way relaying.

“…The simulation results demonstrated that the proposed method was capable of approaching the single user bound for transmission over the gamma-gamma turbulence channel. Additionally, this technology has been adopted as a widely accepted solution for combatting turbulence-induced fading in two-way relay channel (TWRC) FSO systems [12][13][14]. Furthermore, the concept of NC can also be applied to the physical layer that deals with signal reception and modulation, and is known as the physical layer NC (PNC) [15].…”

Physical layer network coding (PNC) improves the throughput in wireless networks by enabling two nodes to exchange information using a minimum number of time slots. The PNC technique is proposed for two-way relay channel free space optical (TWR-FSO) communications with the aim of maximizing the utilization of network resources. The multipair TWR-FSO is considered in this paper, where a single antenna on each pair seeks to communicate via a common receiver aperture at the relay. Therefore, chip-interleaving is adopted as a technique to separate the different transmitted signals at the relay node to perform PNC mapping. Accordingly, this scheme relies on the iterative multiuser technique for detection of users at the receiver. The bit error rate (BER) performance of the proposed system is examined under the combined influences of atmospheric loss, turbulence-induced channel fading and the pointing errors (PEs). By adopting the joint PNC mapping with interleaving and multiuser detection techniques, the BER results show that the proposed scheme can achieve a significant performance improvement against the degrading effects of turbulences and PEs. It is also demonstrated that a larger number of simultaneous users can be supported with this new scheme in establishing a communication link between multiple pairs of nodes in two time slots, thereby improving the channel capacity.
