Fiber Nonlinearity Mitigation by PAPR Reduction in Coherent Optical OFDM Systems via Active Constellation Extension
Fiber Nonlinearity PAPR Optical OFDM Systems Active Constellation Extension
2008/8/4
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
