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...
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...
We demonstrate WDM transmission of three 485-Gb/s CO-OFDM channels with 16-QAM subcarrier-modulation, each received by a single coherent detection step.Transmission over 48 100-km ULAF spans and 12 wa...
We demonstrated experimentally that computationally-efficient digital nonlinearity compensation using backpropagation can increase the nonlinear tolerance of 61.7 Gb/s PDM-CO-OFDM by 2.2 dB in a 500 k...
Evaluation of the back-propagation step size for SPM compensation in a coherent receiver shows that setting step size to the amplifier section length extends the distance of 111Gb/s transmission from ...
