Model-aided Geometrical Shaping of Dual-polarization 4D Formats in the Nonlinear Fiber Channel
Gabriele Liga, Bin Chen, Alex Alvarado
The geometry of dual-polarization four-dimensional constellations is optimized in the optical fiber channel using a recent nonlinear interference model. A 0.27 bit/4D rate gain and…
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…
Modeling of Nonlinear Interference Power for Dual-Polarization 4D Formats
Gabriele Liga, Bin Chen, Astrid Barreiro +1
We assess the accuracy of a recently introduced nonlinear interference model for general dual-polarization 4D formats.~ Unlike previous models for polarization-multiplexed 2D forma…
