Phase noise or frequency noise is a key metrics to evaluate the short term stability of a laser. This property is of a great interest for the applications but delicate to characterize, especially for narrow line-width lasers. In this letter, we demon

High order statistics blind identification algorithms proposed in Terre et al. (2014) and based on the Viterbi & Viterbi Algorithm which suffers on the 2 π / 2 p ambiguity when the order of used statistics is p. In order to remedy this problem, we p
