We review recent advances in understanding Kerr nonlinear limitations in high-capacity long-haul coherent systems, with emphasis on PDM-QPSK transmissions. Both homogeneous and hybrid dispersion-manag...
Impact of Intra-Channel Fiber Nonlinearity on Reduced- Guard-Interval CO-OFDM Transmission

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...
Complexity versus Performance Tradeoff for Fiber Nonlinearity Compensation Using Frequency-Shaped, Multi-Subband Backpropagation

2015/5/21
We investigate the use of an enhanced backpropagation algorithm where subbanding and frequency-shaping by pre- and post-filters are used in the calculation of nonlinearity to enable larger step sizes ...
