Abstract :
We propose and demonstrate an orthogonal labeling scheme using amplitude-shift-keying (ASK) label and polarization-shift-keying (PolSK) payload. The PolSK/ASK orthogonal labeling scheme suffers less frequency chirp than differential-phase-shift-keying/ASK labeling. Receiver sensitivity for payload can be improved by detecting the payload after the removal of ASK label. Performance analysis of the ASK label under different environments of polarization-dependent loss during transmission is also studied.
