Invertible Low-Divergence Coding
Patrick Schulte, Rana Ali Amjad, Thomas Wiegart +1
Several applications in communication, control, and learning require approximating target distributions to within small informational divergence (I-divergence). The additional requ…
Shaped On-Off Keying Using Polar Codes
Thomas Wiegart, Fabian Steiner, Patrick Schulte +1
The probabilistic shaping scheme from Honda and Yamamoto (2013) for polar codes is used to enable power-efficient signaling for on-off keying (OOK). As OOK has a non-symmetric opti…
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…
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…
Experimental Verification of Rate Flexibility and Probabilistic Shaping by 4D Signaling
Fabian Steiner, Francesco Da Ros, Metodi Plamenov Yankov +4
The rate flexibility and probabilistic shaping gain of -dimensional signaling is experimentally tested for short-reach, unrepeated transmission. A rate granularity of 0.5 bits/Q…
Divergence-Optimal Fixed-to-Fixed Length Distribution Matching With Shell Mapping
Patrick Schulte, Fabian Steiner
Distribution matching (DM) transforms independent and Bernoulli(1/2) distributed bits into a sequence of output symbols with a desired distribution. A fixed-to-fixed length, invert…
