On the Performance of Multidimensional Constellation Shaping for Linear and Nonlinear Optical Fiber Channel
Bin Chen, Zhiwei Liang, Shen Li +3
Multidimensional constellation shaping of up to 32 dimensions with different spectral efficiencies are compared through AWGN and fiber-optic simulations. The results show that no c…
Analytical Model of Nonlinear Fiber Propagation for General Dual-Polarization Four-Dimensional Modulation Format
Zhiwei Liang, Bin Chen, Yi Lei +2
Coherent dual-polarization (DP) optical transmission systems encode information on the four available degrees of freedom of an optical field: the two polarization states, each with…
Geometrically-Shaped Multi-Dimensional Modulation Formats in Coherent Optical Transmission Systems
Bin Chen, Yi Lei, Gabriele Liga +4
Shaping modulation formats in multi-dimensional (MD) space is an effective approach to harvest spectral efficiency gains in both the additive white Gaussian noise (AWGN) channel an…
Analytical SNR Prediction in Long-Haul Optical Transmission using General Dual-Polarization 4D Formats
Zhiwei Liang, Bin Chen, Yi Lei +2
Nonlinear interference models for dual-polarization 4D (DP-4D) modulation have only been used so far to predict signal-signal nonlinear interference. We show that including the sig…
Shaped Four-Dimensional Modulation Formats for Optical Fiber Communication Systems
Bin Chen, Gabriele Liga, Yi Lei +4
We review the design of multidimensional modulations by maximizing generalized mutual information and compare the maximum transmission reach of recently introduced 4D formats. A mo…
Low-Complexity Geometrical Shaping for 4D Modulation Formats via Amplitude Coding
Bin Chen, Wei Ling, Yunus Can Gültekin +3
Signal shaping is vital to approach Shannon's capacity, yet it is challenging to implement at very high speeds. For example, probabilistic shaping often requires arithmetic coding…
On Parameter Optimization and Reach Enhancement for the Improved Soft-Aided Staircase Decoder
Yi Lei, Bin Chen, Gabriele Liga +1
The so-called improved soft-aided bit-marking algorithm was recently proposed for staircase codes (SCCs) in the context of fiber optical communications. This algorithm is known as…
A Soft-Aided Staircase Decoder Using Three-Level Channel Reliabilities
Yi Lei, Bin Chen, Gabriele Liga +3
The soft-aided bit-marking (SABM) algorithm is based on the idea of marking bits as highly reliable bits (HRBs), highly unreliable bits (HUBs), and uncertain bits to improve the pe…
Improving HD-FEC decoding via bit marking
Alex Alvarado, Gabriele Liga, Yi Lei +2
We review the recently introduced soft-aided bit-marking (SABM) algorithm and its suitability for product codes. Some aspects of the implementation of the SABM algorithm are discus…
Improved Decoding of Staircase Codes: The Soft-aided Bit-marking (SABM) Algorithm
Yi Lei, Bin Chen, Gabriele Liga +5
Staircase codes (SCCs) are typically decoded using iterative bounded-distance decoding (BDD) and hard decisions. In this paper, a novel decoding algorithm is proposed, which partia…
