Abstract :
We propose an approach based on constant envelope modulation to mitigate fiber induced nonlinearities in CO-OFDM systems. The extensive simulation results demonstrate that the proposed scheme not only greatly mitigates the nonlinear sensitivity of CO-OFDM transmissions but also avoids the severe nonlinear tolerance degradation caused by inline dispersion compensation.
