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…
Nonlinear Interference Analysis of Probabilistic Shaping vs. 4D Geometrically Shaped Formats
Bin Chen, Chigo Okonkwo, Alex Alvarado
Performance trade-offs between linear shaping and nonlinear tolerance of the recently introduced 4D orthant-symmetric 128-ary modulation format are investigated. Numerical simulati…
Complexity-Adjustable SC Decoding of Polar Codes for Energy Consumption Reduction
Haotian Zheng, Bin Chen, Luis F. Abanto-Leon +2
This paper proposes an enhanced list-aided successive cancellation stack (ELSCS) decoding algorithm with adjustable decoding complexity. In addition, a logarithmic likelihood ratio…
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…
