How to Increase the Achievable Information Rate by Per-Channel Dispersion Compensation
Kamran Keykhosravi, Marco Secondini, Giuseppe Durisi +1
Deploying periodic inline chromatic dispersion compensation enables reducing the complexity of the digital back propagation (DBP) algorithm. However, compared with nondispersion-ma…
Nonlinearity Mitigation in WDM Systems: Models, Strategies, and Achievable Rates
Marco Secondini, Erik Agrell, Enrico Forestieri +2
After reviewing models and mitigation strategies for interchannel nonlinear interference (NLI), we focus on the frequency-resolved logarithmic perturbation model to study the coher…
Pilot-Aided Joint-Channel Carrier-Phase Estimation in Space-Division Multiplexed Multicore Fiber Transmission
Arni F. Alfredsson, Erik Agrell, Henk Wymeersch +4
The performance of pilot-aided joint-channel carrier-phase estimation (CPE) in space-division multiplexed multicore fiber (MCF) transmission with correlated phase noise is studied.…
Exploiting AWG Free Spectral Range Periodicity in Distributed Multicast Architectures
Kamran Keykhosravi, Houman Rastegarfar, Nasser Peyghambarian +1
Modular optical switch architectures combining wavelength routing based on arrayed waveguide grating (AWG) devices and multicasting based on star couplers hold promise for flexibly…
Hierarchical Distribution Matching for Probabilistically Shaped Coded Modulation
Tsuyoshi Yoshida, Magnus Karlsson, Erik Agrell
The implementation difficulties of combining distribution matching (DM) and dematching (invDM) for probabilistic shaping (PS) with soft-decision forward error correction (FEC) codi…
Iterative Detection and Phase-Noise Compensation for Coded Multichannel Optical Transmission
Arni F. Alfredsson, Erik Agrell, Henk Wymeersch
The problem of phase-noise compensation for correlated phase noise in coded multichannel optical transmission is investigated. To that end, a simple multichannel phase-noise model…
