Scalable Polar Code Construction for Successive Cancellation List Decoding: A Graph Neural Network-Based Approach
Yun Liao, Seyyed Ali Hashemi, Hengjie Yang +1
While constructing polar codes for successive-cancellation decoding can be implemented efficiently by sorting the bit-channels, finding optimal polar codes for cyclic-redundancy-ch…
Adaptive Read Thresholds for NAND Flash
Borja Peleato, Rajiv Agarwal, John Cioffi +2
A primary source of increased read time on NAND flash comes from the fact that in the presence of noise, the flash medium must be read several times using different read threshold…
Successive Syndrome-Check Decoding of Polar Codes
Seyyed Ali Hashemi, Marco Mondelli, John Cioffi +1
A two-part successive syndrome-check decoding of polar codes is proposed with the first part successively refining the received codeword and the second part checking its syndrome.…
A Tree Search Approach for Maximum-Likelihood Decoding of Reed-Muller Codes
Seyyed Ali Hashemi, Nghia Doan, Warren J. Gross +2
A low-complexity tree search approach is presented that achieves the maximum-likelihood (ML) decoding performance of Reed-Muller (RM) codes. The proposed approach generates a bit-f…
Parallelism versus Latency in Simplified Successive-Cancellation Decoding of Polar Codes
Seyyed Ali Hashemi, Marco Mondelli, Arman Fazeli +3
This paper characterizes the latency of the simplified successive-cancellation (SSC) decoding scheme for polar codes under hardware resource constraints. In particular, when the nu…
Construction of Polar Codes with Reinforcement Learning
Yun Liao, Seyyed Ali Hashemi, John Cioffi +1
This paper formulates the polar-code construction problem for the successive-cancellation list (SCL) decoder as a maze-traversing game, which can be solved by reinforcement learnin…
