A Low-Complexity Improved Successive Cancellation Decoder for Polar Codes
Orion Afisiadis, Alexios Balatsoukas-Stimming, Andreas Burg
Under successive cancellation (SC) decoding, polar codes are inferior to other codes of similar blocklength in terms of frame error rate. While more sophisticated decoding algorith…
Baseband and RF Hardware Impairments in Full-Duplex Wireless Systems: Experimental Characterisation and Suppression
Alexios Balatsoukas-Stimming, Andrew Charles Mallory Austin, Pavle Belanovic +1
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 s…
On Metric Sorting for Successive Cancellation List Decoding of Polar Codes
Alexios Balatsoukas-Stimming, Mani Bastani Parizi, Andreas Burg
We focus on the metric sorter unit of successive cancellation list decoders for polar codes, which lies on the critical path in all current hardware implementations of the decoder.…
A Signal Processor for Gaussian Message Passing
Harald Kröll, Stefan Zwicky, Reto Odermatt +3
In this paper, we present a novel signal processing unit built upon the theory of factor graphs, which is able to address a wide range of signal processing algorithms. More specifi…
Density Evolution for Min-Sum Decoding of LDPC Codes Under Unreliable Message Storage
Alexios Balatsoukas-Stimming, Andreas Burg
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 mode…
Faulty Successive Cancellation Decoding of Polar Codes for the Binary Erasure Channel
Alexios Balatsoukas-Stimming, Andreas Burg
We study faulty successive cancellation decoding of polar codes for the binary erasure channel. To this end, we introduce a simple erasure-based fault model and we show that, under…
LLR-based Successive Cancellation List Decoding of Polar Codes
Alexios Balatsoukas-Stimming, Mani Bastani Parizi, Andreas Burg
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 for…
