Improving Nonlinear Precompensation in Direct-Detection Optical OFDM Communications Systems
Nonlinear Precompensation Direct-Detection Optical OFDM Communications Systems
2008/8/4
Carrier boosting at the receiver enables direct detection optical OFDM (DDO-OFDM) to outperform coherent OOFDM in the nonlinear limit. Boosting also improves the effectiveness of nonlinearity precompe...
Experimental Demonstration of 1600 km SSMF Transmission of a Generalized Direct Detection Optical Virtual SSB-OFDM System
SSMF Transmission Direct Detection Optical Virtual SSB-OFDM System
2008/7/30
We experimentally demonstrate a generalized VSSB-OFDM format that judiciously determines the frequency gap between an inserted RF tone and the signal. The proposed scheme for 10 Gbps exhibits ~3 dB pe...
