PAM-6 Coded Modulation for IM/DD Channels with a Peak-Power Constraint
Tobias Prinz, Thomas Wiegart, Daniel Plabst +4
Coded modulation with probabilistic amplitude shaping (PAS) is considered for intensity modulation/direct detection channels with a transmitter peak-power constraint. PAS is used t…
Probabilistic Parity Shaping for Linear Codes
Georg Böcherer, Diego Lentner, Alessandro Cirino +1
Linear layered probabilistic shaping (LLPS) is proposed, an architecture for linear codes to efficiently encode to shaped code words. In the previously proposed probabilistic ampli…
Polar-Coded Pulse Position Modulation for the Poisson Channel
Delcho Donev, Georg Böcherer
A polar-coded modulation scheme for deep-space optical communication is proposed. The photon counting Poisson channel with pulse position modulation (PPM) is considered. We use the…
Blind Decoding-Metric Estimation for Probabilistic Shaping via Expectation Maximization
Fabian Steiner, Patrick Schulte, Georg Böcherer
An unsupervised learning approach based on expectation maximization is proposed to obtain the parameters of a soft decision forward error correction decoding metric for probabilist…
Flexible IR-HARQ Scheme for Polar-Coded Modulation
Peihong Yuan, Fabian Steiner, Tobias Prinz +1
A flexible incremental redundancy hybrid auto- mated repeat request (IR-HARQ) scheme for polar codes is proposed based on dynamically frozen bits and the quasi-uniform puncturing (…
Approaching Waterfilling Capacity of Parallel Channels by Higher Order Modulation and Probabilistic Amplitude Shaping
Fabian Steiner, Georg Böcherer, Patrick Schulte
Parallel, additive white Gaussian noise (AWGN) channels with an average sum power constraint are considered. It is shown how the waterfilling Shannon capacity can be approached by…
