A Generalized Adjusted Min-Sum Decoder for 5G LDPC Codes: Algorithm and Implementation
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Yifei Shen, Yuqing Ren, Hassan Harb
5G New Radio (NR) has stringent demands on both performance and complexity for the design of low-density parity-check (LDPC) decoding algorithms and corresponding VLSI implementations. Furthermore, decoders must fully support the wide range of all 5G NR bl ...
Ieee-Inst Electrical Electronics Engineers Inc2024Polarization-Adjusted Convolutional (PAC) Codes: Sequential Decoding vs List Decoding
Andreas Peter Burg, Mohammad Rowshan
In the Shannon lecture at the 2019 International Symposium on Information Theory (ISIT), Arikan proposed to employ a one-to-one convolutional transform as a pre-coding step before the polar transform. The resulting codes of this concatenation are called po ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021From LDPC Block to LDPC Convolutional Codes: Capacity, Stability, and Universality
In his landmark paper "A Mathematical Theory of Communication," the founding father of information theory and coding theory, Claude E. Shannon, established the largest rate at which reliable communication is possible and he revealed that the key to this re ...
EPFL2019High-Speed Wireline Link Design
High-speed serial links are a crucial application of semiconductor technology and have been the enabler of the scaling of computing systems. The increasing data-rate requirements of these links have only been partially satisfied by advancements in process ...
EPFL2017Comparison of Polar Decoders with Existing Low-Density Parity-Check and Turbo Decoders
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pascal Giard
Polar codes are a recently proposed family of provably capacity-achieving error-correction codes that received a lot of attention. While their theoretical properties render them interesting, their practicality compared to other types of codes has not been ...
Ieee2017Hardware implementation aspects of polar decoders and ultra high-speed LDPC decoders
Alexios Konstantinos Balatsoukas Stimming
The goal of channel coding is to detect and correct errors that appear during the transmission of information. In the past few decades, channel coding has become an integral part of most communications standards as it improves the energy-efficiency of tran ...
EPFL2016A Multi-Gbps Unrolled Hardware List Decoder Systematic Polar Code
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Thomas Christoph Müller, Pascal Giard
Polar codes are a new class of block codes with an explicit construction that provably achieve the capacity of various communications channels, even with the low-complexity successive-cancellation (SC) decoding algorithm. Yet, the more complex successive-c ...
2016Multiuser Random Coding Techniques for Mismatched Decoding
Jonathan Mark Scarlett, Albert Guillén i Fàbregas
This paper studies multiuser random coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, an error exponent is obtained that is tight with respect to the ensem ...
Institute of Electrical and Electronics Engineers2016High-Speed Link With Trellis-Coded Modulation and Reed Solomon Coding
Andreas Peter Burg, Thomas Toifl, Giovanni Cherubini
A high-performance low-latency transmission system based on a concatenated code consisting of inner four-dimensional five-level pulse-amplitude-modulation (5-PAM) trellis-coded modulation and an outer Reed-Solomon (RS) code is proposed for a high-speed dat ...
Ieee2016Density Evolution for Min-Sum Decoding of LDPC Codes Under Unreliable Message Storage
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming
We analyze the performance of quantized min-sum decoding of low-density parity-check codes under unreliable message storage. To this end, we introduce a simple bit-level error model and show that decoder symmetry is preserved under this model. Subsequently ...
