A Low-Complexity Probabilistic Amplitude Shaping With Short Linear Block Codes
IEEE Transactions on Communications, 2021 We propose a new probabilistic amplitude shaping (PAS) scheme based on short linear block codes. In the proposed system, the capacity-approaching signal distribution is generated in the process of decoding linear block codes for a given information bit ...

A modified probabilistic amplitude shaping scheme to use sign-bit-like shaping with a BICM [PDF]
2023 IEEE Information Theory Workshop (ITW), 2023 On the one hand, sign-bit shaping is a popular shaping scheme where the conditional probability of the sign bit is made non-equiprobable. On the other hand, probabilistic amplitude shaping (PAS) is a popular coding scheme, to combine shaping and a bit ...

FPGA based modified multi-repeat distribution matcher for probabilistic amplitude shaping
Nexo Revista Científica, 2023 The technique of probabilistic amplitude modulation, based on distribution matching, has garnered considerable attention in recent years as a means to enhance spectral efficiency and diminish the constellation energy of coded modulation.

Probabilistic Amplitude Shaping for Continuous-Variable Quantum Key Distribution With Discrete Modulation Over a Wiretap Channel [PDF]
IEEE Transactions on Communications, 2022 To achieve the maximum information transfer and face a possible eavesdropper, the samples transmitted in continuous-variable quantum key distribution (CV-QKD) protocols are to be drawn from a continuous Gaussian distribution.

Rate-Adaptive Concatenated Multi-Level Coding With Novel Probabilistic Amplitude Shaping
IEEE Transactions on Communications, 2022 This paper proposes a new probabilistic amplitude shaping (PAS) approach for concatenated two-level multi-level coding (MLC). The proposed system is based on a concatenated forward error correction (FEC) scheme where outer codes are serially concatenated

Mitigating error enhancement of probabilistic amplitude shaping by error-correctable shaping.
Optics ExpressProbabilistic amplitude shaping improves the signal-to-noise ratio requirement, although it suffers from burst errors in the inverse process of the distribution matcher (DM), which negatively enhances bit-error rate (BER). To mitigate this, we propose an

Probabilistic Amplitude Shaping With Hard Decision Decoding and Staircase Codes [PDF]
Journal of Lightwave Technology, 2017 We consider probabilistic amplitude shaping (PAS) as a means of increasing the spectral efficiency of fiber-optic communication systems. In contrast to previous works in the literature, we consider probabilistic shaping with hard decision decoding (HDD).

Information Rates and Error Exponents for Probabilistic Amplitude Shaping [PDF]
2018 IEEE Information Theory Workshop (ITW), 2018 Probabilistic Amplitude Shaping (PAS) is a codedmodulation scheme in which the encoder is a concatenation of a distribution matcher with a systematic Forward Error Correction (FEC) code. For reduced computational complexity the decoder can be chosen as a
