Impact of Intra-Channel Fiber Nonlinearity on Reduced-Guard-Interval CO-OFDM Transmission

Not Accessible

Your library or personal account may give you access


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 can be used, the RGI CO-OFDM system also demonstrates better non-linearity tolerance than conventional CO-OFDM with larger FFT sizes.
