High Throughput Polar Code Decoders with Information Bottleneck Quantization

Autor: Kestel, Claus, Johannsen, Lucas, Wehn, Norbert

In digital baseband processing, the forward error correction (FEC) unit belongs to the most demanding components in terms of computational complexity and power consumption. Hence, efficient implementation of FEC decoders is crucial for next generatio

Row-Merged Polar Codes: Analysis, Design and Decoder Implementation

Autor: Zunker, Andreas, Geiselhart, Marvin, Johannsen, Lucas, Kestel, Claus, Brink, Stephan ten, Vogt, Timo, Wehn, Norbert

Row-merged polar codes are a family of pre-transformed polar codes (PTPCs) with little precoding overhead. Providing an improved distance spectrum over plain polar codes, they are capable to perform close to the finite-length capacity bounds. However

Hydrological and pedological effects of combining Italian alder and blackberries in an agroforestry windbreak system in South Africa

Autor: S. Hoffmeister, R. Bohn Reckziegel, B. du Toit, S. K. Hassler, F. Kestel, R. Maier, J. P. Sheppard, E. Zehe

Publikováno v: Hydrology and Earth System Sciences, Vol 28, Pp 3963-3982 (2024)

The Western Cape in South Africa is a water-scarce region which will likely receive less rainfall and higher air temperatures under projected climate change scenarios. The integration of trees within agricultural systems provides an effective measure

Successive Cancellation Automorphism List Decoding of Polar Codes

Autor: Johannsen, Lucas, Kestel, Claus, Geiselhart, Marvin, Vogt, Timo, Brink, Stephan ten, Wehn, Norbert

The discovery of suitable automorphisms of polar codes gained a lot of attention by applying them in Automorphism Ensemble Decoding (AED) to improve the error-correction performance, especially for short block lengths. This paper introduces Successiv

The Impact of Feature Selection and Transformation on Machine Learning Methods in Determining the Credit Scoring

Autor: Koc, Oguz, Ugur, Omur, Kestel, A. Sevtap

Publikováno v: Oguz Koc. Comparison of Machine Learning Algorithms on Consumer Credit Classification. M.Sc. Thesis, Middle East Technical University, 2019

Banks utilize credit scoring as an important indicator of financial strength and eligibility for credit. Scoring models aim to assign statistical odds or probabilities for predicting if there is a risk of nonpayment in relation to many other factors

Automorphism Ensemble Polar Code Decoders for 6G URLLC

Autor: Kestel, Claus, Geiselhart, Marvin, Johannsen, Lucas, Brink, Stephan ten, Wehn, Norbert

The URLLC scenario in the upcoming 6G standard requires low latency and ultra reliable transmission, i.e., error correction towards ML performance. Achieving near-ML performance is very challenging especially for short block lengths. Polar codes are
