The authors of the subject paper [1] would like add an important reference [2], which deals with modulation format recognition for signals in wireless networks. The authors were not aware of [2] at the time of publication because they were focusing on modulation format recognition for signals in optical networks. They regret this omission.
Disclosures
The authors declare no conflicts of interest.
