Probabilistic Shaping for Finite Blocklengths: Distribution Matching and Sphere Shaping [PDF]
Entropy, 2020 In this paper, we provide a systematic comparison of distribution matching (DM) and sphere shaping (SpSh) algorithms for short blocklength probabilistic amplitude shaping. For asymptotically large blocklengths, constant composition distribution matching (

Partial Enumerative Sphere Shaping [PDF]
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019 The dependency between the Gaussianity of the input distribution for the additive white Gaussian noise (AWGN) channel and the gap-to-capacity is discussed.

Approximate Enumerative Sphere Shaping [PDF]
2018 IEEE International Symposium on Information Theory (ISIT), 2018 Enumerative sphere shaping of N-dimensional constellations is discussed. It is proven that a finite-precision number representation is suitable for use in two enumerative indexing algorithms: Enumerative sphere shaping and Divide Conquer (DC) shaping. This representation decreases the storage complexities of these methods significantly. DC is the basis

Shaping lightwaves in time and frequency for optical fiber communication
Nature Communications, 2022 The authors report nonlinear interference changes with shaping block length, modulation symbol rate, and chromatic dispersion when sphere-shaped lightwaves propagate through optical fibre, and suggest a method to predict that change.

Medial Spheres for Shape Approximation [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010 We study the problem of approximating a 3D solid with a union of overlapping spheres. In comparison with a state-of-the-art approach, our method offers more than an order of magnitude speedup and achieves a tighter approximation in terms of volume difference with the original solid while using fewer spheres.

Hierarchical Distribution Matching for Probabilistic Amplitude Shaping
Entropy, 2020 Probabilistic amplitude shaping—implemented through a distribution matcher (DM)—is an effective approach to enhance the performance and the flexibility of bandwidth-efficient coded modulations. Different DM structures have been proposed in the literature.
