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 …

A distribution matcher (DM) maps a binary input sequence into a block of nonuniformly
distributed symbols. To facilitate the implementation of shaped signaling, fast DM solutions …

Abstract Systems and methods for constellation shaping of M-QAM modulation formats in
optical transport networks may receive binary data to be transmitted as an optical signal and …

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

In this paper, we propose a receiver architecture capable of compensating for a time-varying
signal distortion induced by the transmitter analog components. In the proposed …
