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 A RSS fingerprint database constructed at the offline phase may be outdated for online phase, which may significantly degrade the localization performance.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...
