Impact of Intra-Channel Fiber Nonlinearity on Reduced- Guard-Interval CO-OFDM Transmission
Coherent communications Fiber optics communications Modulation
2015/5/26
Channel estimation for a reduced-guard-interval (RGI) CO-OFDM system shows a unique dependence on the training symbol design in the presence of intra-channel nonlinearities.Because smaller FFT sizes c...
Reduced-Guard-Interval CO-OFDM with Overlapped Frequency-Domain CD and PMD Equalization
Reduced-Guard-Interval CO-OFDM Overlapped Frequency-Domain CD PMD Equalization
2015/5/25
We propose an algorithm for CO-OFDM receivers to perform overlapped frequency-domain CD and PMD equalization before OFDM symbol demodulation. This approach enables OFDM transmission with a small cycli...
