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

Distribution matching is a fixed-length invertible mapping from a uniformly distributed bit
sequence to shaped amplitudes and plays an important role in the probabilistic amplitude …

The implementation difficulties of combining distribution matching (DM) and dematching
(invDM) for probabilistic shaping (PS) with soft-decision forward error correction (FEC) …

In this paper, we provide a systematic comparison of distribution matching (DM) and sphere
shaping (SpSh) algorithms for short blocklength probabilistic amplitude shaping. For …

In this paper, we construct variable-length prefix-free codes that are optimal (or near-
optimal) in the sense that no (or few) other codes of the same cardinality can achieve a …

In this paper, we review the concept of multiset-partition-based distribution matching. We
then characterize performance over short block lengths of 20, 40, and 80 symbols, and with …

An estimation method for the nonlinear signal-to-noise ratio (SNR) is extended to
simultaneously identify the shaping distribution for rate-adaptive probabilistically shaped …

In this article, we analyze the performance of probabilistic shaping (PS) color shift keying
(CSK) modulated visible light communication (VLC) systems. Specifically, we have …

In this paper, a high-security chaos encryption with dynamic probability for 16-carrier-less
amplitude/phase (CAP) PON is proposed by using two-layer chaos map with feedforward …

We propose and experimentally demonstrate the intensity-modulation direct-detection
(IM/DD) transmission employing low-density parity-check (LDPC) coded probabilistic …
