A Flip-Syndrome-List Polar Decoder Architecture for Ultra-Low-Latency Communications
IEEE Access, 2019 We consider practical hardware implementation of polar decoders. To reduce latency due to the serial nature of successive cancellation, existing optimizations improve parallelism with two approaches, i.e., multi-bit decision or reduced path splitting. In

Progressive Bit-Flipping Decoding of Polar Codes: A Critical-Set Based Tree Search Approach
IEEE Access, 2018 In successive cancellation (SC) polar decoding, an incorrect estimate of any prior unfrozen bit may bring about severe error propagation in the following decoding, and thus it is desirable to find out and correct an error as early as possible.

Hardware Architecture for List Successive Cancellation Decoding of Polar Codes [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2014 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 cumbersome part of list SC decoding.

Successive cancellation list polar decoder using log-likelihood ratios [PDF]
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014 Successive cancellation list (SCL) decoding algorithm is a powerful method that can help polar codes achieve excellent error-correcting performance. However, the current SCL algorithm and decoders are based on likelihood or log-likelihood forms, which render high hardware complexity. In this paper, we propose a log-likelihood-ratio (LLR)-based SCL (LLR-
