Abstract :
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 nonlinearity tolerance than conventional CO-OFDM with larger FFT sizes.
