Self-Pilot Tone Based Adaptive Threshold RZ-OOK Decision for Free-Space Optical Communications
This paper studies a novel self-pilot tone based adaptive threshold return-to-zero on-off keying (RZ-OOK) decision for free-space optical (FSO) communications. RZ-OOK has the characteristics of impulse series in the spectrum. Therefore, these impulses can be utilized as the pilot tones of the transm...
