On the construction of protograph based SC-LDPC codes for windowed decoding
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018In this paper we optimize spatially coupled protographs for window decoding (WD) and arbitrary rate. Previous studies found that the belief propagation (BP) threshold of spatially coupled code ensembles achieves the maximum a posteriori (MAP) threshold of their underlying block code ensemble.

Latency Analysis and Architecture Design of Simplified SC Polar Decoders
IEEE Transactions on Circuits and Systems II: Express Briefs, 2014Recently, a low-latency decoding scheme called the simplified successive cancellation (SSC) algorithm has been proposed for polar codes. In this brief, we present the first systematic approach to formally derive the SSC decoding latency for any given polar code.

Parity Check Aided SC-Flip Decoding Algorithms for Polar Codes
IEEE Transactions on Vehicular Technology, 2021When polar codes are decoded by the successive cancellation (SC) decoding algorithm, erroneously decoded non-frozen bits are caused by either channel noise or error propagation. SC-Flip algorithms aim to improve error performance by first identifying erroneous hard decisions due to channel noise and then flipping them during the decoding process to ...

Simplified multi-bit SC list decoding for polar codes
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016In this paper, we propose a simplified multi-bit successive cancellation list (SMSCL) decoding method for polar codes. In the proposed SMSCL decoding, frozen bits are ignored, and multiple information bits are intermediately decoded at each decision step.

A Hybrid OSD-SC Decoding Algorithm for Polar Codes
2019 IEEE 3rd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2019In this paper, we propose a low complexity hybrid ordered statistics decoding (OSD) successive cancellation (SC) decoding algorithm for the polar codes. By replacing smaller size SC decoder with OSD decoder, we can improve the error correcting performance of the SC algorithm.

Neural Network Aided SC Decoder for Polar Codes
2018 IEEE 4th International Conference on Computer and Communications (ICCC), 2018Theoretically, conventional decoders for polar codes can be entirely replaced by neural network (NN) with enough size and enough training, which called NN decoder. But the exponentially increasing training complexity becomes unacceptable when information length increases, which means only decoders for short codes can be trained practically.

An FPGA-based accelerator for rapid simulation of SC decoding of polar codes
2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS), 2015In this paper we present an FPGA-based system for rapid frame error rate simulations of successive cancellation decoding of polar codes. Our system is implemented on a Xilinx Virtex-7 XC7VX485T FPGA and it supports polar codes of any rate and of blocklength up to N = 1024 bits on that device.

The Hardware Acceleration of SC Decoder for Polar Code towards HLS Optimization
2018 International SoC Design Conference (ISOCC), 2018With the extensive use of hardware acceleration for complex algorithms, fast hardware implementations of those algorithms with HLS become necessary. However, high performance hardware generated with HLS needs numerous skills and the successive-cancellation (SC) decoding algorithm for polar code, which is widely used in 5G era, can’t be converted from c

Reduced-latency LLR-based SC List Decoder for Polar Codes
Proceedings of the 25th edition on Great Lakes Symposium on VLSI, 2015Polar codes, as the new generation of channel codes, have potential applications in communication and storage systems. Successive-cancellation list (SCL) algorithm is the main decoding approach for improving the error-correcting performance of polar codes.
