Coding for Optical Communications -- Can We Approach the Shannon Limit With Low Complexity?
Alexandre Graell i Amat, Gianluigi Liva, Fabian Steiner
Approaching capacity with low complexity is a very challenging task. In this paper, we review and compare three promising coding solutions to achieve that, which are suitable for f…
Shaped On-Off Keying Using Polar Codes
Thomas Wiegart, Fabian Steiner, Patrick Schulte +1
The probabilistic shaping scheme from Honda and Yamamoto (2013) for polar codes is used to enable power-efficient signaling for on-off keying (OOK). As OOK has a non-symmetric opti…
Probabilistic Parity Shaping for Linear Codes
Georg Böcherer, Diego Lentner, Alessandro Cirino +1
Linear layered probabilistic shaping (LLPS) is proposed, an architecture for linear codes to efficiently encode to shaped code words. In the previously proposed probabilistic ampli…
One and Two Bit Message Passing for SC-LDPC Codes with Higher-Order Modulation
Fabian Steiner, Emna Ben Yacoub, Balazs Matuz +2
Low complexity decoding algorithms are necessary to meet data rate requirements in excess of 1 Tbps. In this paper, we study one and two bit message passing algorithms for belief p…
Protograph-Based LDPC Code Design for Probabilistic Shaping with On-Off Keying
Alexandru Dominic Git, Balázs Matuz, Fabian Steiner
This work investigates protograph-based LDPC codes for the AWGN channel with OOK modulation. A non-uniform distribution of the OOK modulation symbols is considered to improve the p…
Design of Polar Codes for Parallel Channels with an Average Power Constraint
Thomas Wiegart, Tobias Prinz, Fabian Steiner +1
Polar codes are designed for parallel binary-input additive white Gaussian noise (BiAWGN) channels with an average power constraint. The two main design choices are: the mapping be…
