Classification of Automorphisms for the Decoding of Polar Codes
Charles Pillet, Valerio Bioglio, Ingmar Land
This paper proposes new polar code design principles for the low-latency automorphism ensemble (AE) decoding. Our proposal permits to design a polar code with the desired automorph…
High-performance low-complexity error pattern generation for ORBGRAND decoding
Carlo Condo, Valerio Bioglio, Ingmar Land
Guessing Random Additive Noise Decoding (GRAND) is a recently proposed decoding method searching for the error pattern applied to the transmitted codeword. Ordered reliability bit…
Staircase codes with non-systematic polar codes
Carlo Condo, Valerio Bioglio, Charles Pillet +1
In this work we propose an encoding and decoding framework for staircase codes based on non-systematic polar codes as component codes. The staircase structure allows for efficient…
Polar Codes for Automorphism Ensemble Decoding
Charles Pillet, Valerio Bioglio, Ingmar Land
In this paper we deal with polar code automorphisms that are beneficial under low-latency automorphism ensemble (AE) decoding, and we propose polar code designs that have such auto…
Fast-SCAN decoding of Polar Codes
Charles Pillet, Carlo Condo, Valerio Bioglio
Polar codes are able to achieve the capacity of memoryless channels under successive cancellation (SC) decoding. Soft Cancellation (SCAN) is a soft-output decoder based on the SC s…
SCAN List Decoding of Polar Codes
Charles Pillet, Carlo Condo, Valerio Bioglio
In this paper we propose an enhanced soft cancellation (SCAN) decoder for polar codes based on decoding stages permutation. The proposed soft cancellation list (SCANL) decoder runs…
