Coded Modulation and Forward Error Correction for Fiber-Optic Communication
Differentially detected binary phase shift keying (D-BPSK) has recently attracted a lot of attention for use in ultra-long-haul optical wavelength-division multiplexed (WDM) systems. The main reason is that D-BPSK gives a substantial (about 2.5 dB) detection energy gain over direct-detection on-off keying (DD-OOK). Furthermore, D-BPSK tends to suppress fiber nonlinear penalties such as those due to cross-phase modulation better than OOK. Although D-BPSK is an old technique, the importance of its combined linear and nonlinear gains has been recognized only recently. This motivated an investigation into the performance of several modulation and detection schemes that are suited for high-speed fiber-optic communication.
