A 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 ...

Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Andrew Charles Mallory Austin

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...

LLR-Based Successive Cancellation List Decoding of Polar Codes

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming

We show that successive cancellation list decoding can be formulated exclusively using log-likelihood ratios. In addition to numerical stability, the log-likelihood ratio based formulation has useful properties that simplify the sorting step involved in su ...

Enabling Complexity-Performance Trade-Offs for Successive Cancellation Decoding of Polar Codes

Andreas Peter Burg, Georgios Karakonstantis, Alexios Konstantinos Balatsoukas Stimming

Polar codes are one of the most recent advancements in coding theory and they have attracted significant interest. While they are provably capacity achieving over various channels, they have seen limited practical applications. Unfortunately, the successiv ...

LLR-based Successive Cancellation List Decoding of Polar Codes

Mani Bastaniparizi, Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming

We present an LLR-based implementation of the successive cancellation list (SCL) decoder. To this end, we associate each decoding path with a metric which (i) is a monotone function of the path’s likelihood and (ii) can be computed efﬁciently from the chan ...

Density 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 ...

Hardware Architecture for List Successive Cancellation Decoding of Polar Codes

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming

This brief presents a hardware architecture and algorithmic improvements for list successive cancellation (SC) decoding of polar codes. More specifically, we show how to completely avoid copying of the likelihoods, which is algorithmically the most cumbers ...

A Parallelized Layered QC-LDPC Decoder for IEEE 802.11ad

Alessandro Cevrero, Andreas Peter Burg, Nicholas Alexander Preyss, Alexios Konstantinos Balatsoukas Stimming

We present a doubly parallelized layered quasi-cyclic low density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a nonparallelized layered decoder and, thus, retains its favorable ...
