Probabilistic Amplitude Shaping
Foundations and Trends® in Communications and Information Theory, 2023Summary: Probabilistic amplitude shaping (PAS) proposed in [\textit{G. Böcherer} et al., ``Bandwidth efficient and rate-matched low-density parity-check coded modulation'', IEEE Trans. Commun. 63, No. 12, 4651--4665 (2015; \url{doi:10.1109/TCOMM.2015.2494016})] is a practical architecture for combining non-uniform distributions on higher-order ...

Energy-Based Arithmetic Coding Methods for Probabilistic Amplitude Shaping
GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023We consider probabilistic amplitude shaping (PAS) of quadrature amplitude modulation (QAM) constellations. Our investigation stems from a consideration of practically achieving optimal shaping gain with very low complexity. In this paper we introduce two

A probabilistic amplitude shaping scheme on amplitude and phase shift keying modulation
5th International Conference on Information Science, Electrical, and Automation Engineering (ISEAE 2023), 2023The probabilistic amplitude shaping(PAS) scheme based on amplitude shift keying(ASK) has attracted much attention as a signal-shaping solution. However, due to the limitation of nonlinear effects in practical applications, the robustness of the ASK ...

Approximation Methods for Enumerating Sequences for Probabilistic Amplitude Shaping
2023 IEEE International Symposium on Information Theory (ISIT), 2023We consider approximation of N(n, E) and Nc(n, E), the number of sequences of ASK symbols of length n with energy equal to E and at most equal to E, respectively.

Low-complexity Channel-polarized Multilevel Coding for Probabilistic Amplitude Shaping
Optical Fiber Communication Conference (OFC) 2022, 2022We propose a low-complexity FEC scheme for PAS, which applies SD-FEC to unreliable bits converted by channel polarization. It reduces the complexity by up to 83% compared with changing the decoding iterations in PAS. © 2021 The Author(s)

Probabilistic Amplitude Shaping Performance over FSO Atmospheric Turbulence Channels
2024 3rd International Conference on Advances in Engineering Science and Technology (AEST)Free-space optics (FSO) shows great promise for ultra-high-capacity wireless communication. Still, it faces limitations due to power fluctuations from atmospheric turbulence, weather, and pointing errors.

Polar coded probabilistic amplitude shaping for short packets
2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017Polar codes with dynamically frozen bits are combined with probabilistic amplitude shaping (PAS). At the transmitter, constant composition distribution matching (CCDM) is used to match uniformly distributed input bits to symbols having a desired amplitude distribution.

Simple Deshaping Scheme to suppress Burst Error for Probabilistic Amplitude Shaping
2024 IEEE Opto-Electronics and Communications Conference (OECC)Probabilistic amplitude shaping (PAS) is a practical architecture realizing probabilistic shaping to overcome the signal-noise ratio (SNR) gap toward Shannon limit. In PAS, the deshaper causes the burst errors which are multiple and consecutive errors in
