Demonstraton of Frequency-Domain Averaging Based Channel Estimation for 40-Gb/s CO-OFDM with High PMD
01 January 2009
We experimentally demonstrate the intra-symbol frequency-domain averaging based channel estimation for a 40-Gb/s polarization- division-multiplexed coherent optical OFDM signal with 8-QAM modulation under large polarization-mode-dispersion, showing improved efficiency as compared to the time-domain averaging based scheme.
