Spectrally Efficient Direct-Detected Optical OFDM Transmission Using Carrier-Data Timely Multiplexing Technique
Spectrally Efficient Direct-Detected Optical OFDM Transmission Timely Multiplexing Technique
2015/7/17
We timely multiplex the carrier and data symbols for DD-OFDM that improves the spectral efficiency,receiving sensitivity, and tolerances to PMD and optical filtering effects, when compared with the pr...
Joint CD and PMD Compensation for Direct-Detected Optical OFDM Using Polarization-Time Coding Approach
Joint CD PMD Compensation Direct-Detected Optical OFDM Polarization-Time Coding Approach
2015/7/14
We demonstrate a polarization-time coding method for direct-detected OFDM, which provides the signal with immunity against both fibre CD and PMD effects. Further dynamic PTC method is introduced for t...
