A New Probabilistic Constellation Shaping Scheme for APSK Modulation
2021 Iran Workshop on Communication and Information Theory (IWCIT), 2021Probabilistic constellation shaping (PCS) has attracted a lot of attention for increasing the spectral efficiency (SE) in coherent fiber optic communication. Unfortunately, increasing the transmit power could increase non-linear self- and cross-phase modulations due to the Kerr effect in fiber optic. Owing to smaller peak-to-average power ratio (PAPR),

Laser Phase Noise Tolerance of Probabilistically-Shaped Constellations
Optical Fiber Communication Conference, 2018We numerically confirmed that required-OSNR gain was obtained by probabilistically-shaped 64/256 QAM compared with uniformly-shaped 16/64 QAM in not only arbitrary white Gaussian noise condition but also in phase noise condition.

Probabilistic Constellation Shaping for Long-Haul Transmission Systems
OSA Advanced Photonics Congress 2021, 2021We review recent findings and advances in probabilistic constellation shaping for long- haul transmission systems, from terrestrial networks to submarine cable systems, with dispersion- managed and dispersion-unmanaged links.

Probabilistically Constellation Shaped Kramers-Kronig Detection Enabling Reduced CSPR Condition
Conference on Lasers and Electro-Optics, 2022We propose to relax the requirement of carrier-to-signal power ratio in Kramers-Kronig receiver by probabilistically shaping the constellation to avoid destroying minimum phase condition. About 1.5-dB reduction in optimal carrier-to-signal power ratio are observed.
