We discuss digital signal processing (DSP) techniques for self-homodyne detection (SHD), multi-core fiber (MCF) transmission links, and related technologies. We focus on exploiting the reduced phase noise of self-homodyne multi-core fiber (SH-MCF) systems to enable DSP resource savings and describe digital receiver architectures that mixes signal and local(More)
—Analytical models for all-optical phase-sensitive BPSK and QPSK regeneration are presented, metrics for phase and intensity regeneration efficiency are derived. The models are based on the general principle of operation and do not depend on the regenerator's physical structure. They offer the possibility of simple network planning and comparison of(More)
