Abstract
We demonstrate a performance enhanced carrier-phase-recovery (CPR) method for spectral-efficient digital-subcarrier-multiplexing transmissions with two-interleaved-pilot-tones. By reconstructing and compensating transmitter-side and receiver-side laser phase noises separately, equalization-enhance-phase-noise (EEPN) can be circumvented.
