Efficient Probabilistic Parity Shaping for Irregular Repeat-Accumulate LDPC Codes

Diego Lentner, Thomas Wiegart, Richard D. Wesel

Algorithms are presented that efficiently shape the parity bits of systematic irregular repeat-accumulate (IRA) low-density parity-check (LDPC) codes by following the sequential en…

Neural Network Equalizers and Successive Interference Cancellation for Bandlimited Channels with a Nonlinearity

Daniel Plabst, Tobias Prinz, Francesca Diedolo +4

Neural networks (NNs) inspired by the forward-backward algorithm (FBA) are used as equalizers for bandlimited channels with a memoryless nonlinearity. The NN-equalizers are combine…

Neural Network-Based Successive Interference Cancellation for Non-Linear Bandlimited Channels

Daniel Plabst, Tobias Prinz, Francesca Diedolo +4

Reliable communication over bandlimited and non-linear channels usually requires equalization to simplify receiver processing. Equalizers that perform joint detection and decoding…

Optimizing Bipolar Constellations for High-Rate Transmission in Short-Reach Fiber Links with Direct Detection

Thomas Wiegart, Daniel Plabst, Norbert Hanik +1

Bipolar modulation increases the achievable information rate of communication links with direct-detection receivers. This paper optimizes bipolar transmission with a modulator bias…
