On Digital Subcarrier Multiplexing under A Bandwidth Limitation and ASE Noise
Junho Cho, Xi Chen, Greg Raybon +1
We show that digital subcarrier multiplexing (DSM) systems require much greater complexity for Nyquist pulse shaping than single-carrier (SC) systems, and it is a misconception tha…
Digital Interference Mitigation in Space Division Multiplexing Self-Homodyne Coherent Detection
Hanzi Huang, Yetian Huang, Haoshuo Chen +7
We propose a digital interference mitigation scheme to reduce the impact of mode coupling in space division multiplexing self-homodyne coherent detection and experimentally verify…
Does Probabilistic Constellation Shaping Benefit IM-DD Systems without Optical Amplifiers?
Di Che, Junho Cho, Xi Chen
Probabilistic constellation shaping (PCS) has been widely applied to amplified coherent optical transmissions owing to its shaping gain over the uniform signaling and fine-grained…
Full C-Band WDM Transmission of Nonlinearity-Tolerant Probabilistically Shaped QAM over 2824-km Dispersion-Managed Fiber
Junho Cho, Xi Chen, Greg Raybon +3
By tailoring probabilistic constellation shaping (PCS) for nonlinearity tolerance, we experimentally demonstrate up to 1.1 dB increase in signal-to-noise ratio (SNR) and 6.4% incre…
Supply-Power-Constrained Cable Capacity Maximization Using Multi-Layer Neural Networks
Junho Cho, Sethumadhavan Chandrasekhar, Erixhen Sula +9
We experimentally solve the problem of maximizing capacity under a total supply power constraint in a massively parallel submarine cable context, i.e., for a spatially uncoupled sy…
Prefix-Free Code Distribution Matching for 5G New Radio
Junho Cho, Ori Shental
We use prefix-free code distribution matching (PCDM) for rate matching (RM) in some 5G New Radio (NR) deployment scenarios, realizing a wide range of information rates from 1.4 to…
