Experimental Study of Polarization-Switched-QPSK Subcarrier Modulation and Iterative Demapping on Optical OFDM Systems
multiplex achieved OCIS codes
2015/5/21
We demonstrate application of polarization-switched-QPSK subcarrier modulation together with soft-FEC LDPC coding and iterative demapping on OFDM lab system. 4.5dB OSNR-sensitivity improvement versus ...
Digital Lightpath Label Transcoding for Dual-Polarization QPSK Systems
Digital Lightpath Label Transcoding QPSK System
2015/5/15
We introduce digital lightpath labeling for DP-QPSK transmission, using novel binary encoding to embed a polarization-shift-keyed subchannel. An integrated inline polarimeter powers a compact label re...
Performance of Modified Decision-Directed Polarization Control/Demultiplex Algorithm in Coherent QAM Receiver
Coherent communications Optical communications
2015/6/4
A modified decision-directed polarization control and demultiplex algorithm for coherent receivers is evaluated for QAM schemes up to order 256, and compared against the constant-modulus algorithm ada...
QAM Adaptation of Constant-Modulus Algorithm and Differential Phase Compensation for Polarization Demultiplex in Coherent Receiver
QAM Adaptation Constant-Modulus Algorithm Differential Phase Compensation Polarization Demultiplex Coherent Receiver
2015/7/16
The constant modulus algorithm is adapted for QAM signals and complemented with a differential phase compensation. This triples polarization control speed and doubles laser linewidth tolerance.
