Presents corrections to the paper, “Two-way mixed RF/FSO relaying system in the presence of co-channel interference,” (Wang, Z., et al), IEEE Photon. J., vol. 11, no. 2, Apr. 2019, Art. no. 7902516.

RSS fingerprint based indoor localization consists of two phases: offline phase and online phase. A RSS fingerprint database constructed at the offline phase may be outdated for online phase, which may significantly degrade the localization performance. Furthermore, maintaining an RSS fingerprint da...

In this paper, the performance of a two-way mixed radio frequency/free space optical (RF/FSO) relaying system in the presence of co-channel interference (CCI) is investigated. The RF links are modeled as Nakagami-m distribution, and FSO links adopt Gamma-Gamma turbulence model. To improve spectral e...
