We review probabilistic constellation shaping (PCS), which has been a key enabler for
several recent record-setting optical fiber communications experiments. PCS provides both …

A new coded modulation scheme is proposed. At the transmitter, the concatenation of a
distribution matcher and a systematic binary encoder performs probabilistic signal shaping …

Traditionally, digital modulation schemes are bijective (ie, the signal constellation points are
disjunct), and the mapping is unique. Only recently it has been discovered that non-bijective …

Probabilistic amplitude shaping (PAS) has proved to be a promising way to achieve the
shaping gain for an additive white Gaussian noise channel with a distribution matcher (DM) …

This paper focuses on the signal constellation shaping in LDPC coded modulation system. A
novel constellation is presented by combining geometric shaping with probabilistic shaping …

Gallager mapping uses different signal points with different probabilities by assigning
several labels for one signal point, and thus provides a promising approach to achieving …

High-order modulations are necessary to improve the bandwidth efficiency of the satellite
communication system. However, the non-linear characteristic of satellite channels limits the …

We consider a signaling format where the information to be communicated from a single or
multiple transmitters to a receiver is modulated via a superposition of independent data …

In this paper, we integrate the 5G low-density parity-check (LDPC) coded modulation
systems with hybrid shaping, where the centroid-based geometric shaping is implemented …
