LDPC Decoding with Degree-Specific Neural Message Weights and RCQ Decoding
Linfang Wang, Caleb Terrill, Richard Wesel +1
Recently, neural networks have improved MinSum message-passing decoders for low-density parity-check (LDPC) codes by multiplying or adding weights to the messages, where the weight…
ELF Codes: Concatenated Codes with an Expurgating Linear Function as the Outer Code
Richard Wesel, Amaael Antonini, Linfang Wang +3
An expurgating linear function (ELF) is a linear outer code that disallows the low-weight codewords of the inner code. ELFs can be designed either to maximize the minimum distance…
Systematic Transmission With Fountain Parity Checks for Erasure Channels With Stop Feedback
Hengjie Yang, Richard D. Wesel
In this paper, we present new achievability bounds on the maximal achievable rate of variable-length stop-feedback (VLSF) codes operating over a binary erasure channel (BEC) at a f…
Probabilistic Shaping for Asymmetric Channels and Low-Density Parity-Check Codes
Thomas Wiegart, Linfang Wang, Diego Lentner +1
An algorithm is proposed to encode low-density parity-check (LDPC) codes into codewords with a non-uniform distribution. This enables power-efficient signalling for asymmetric chan…
Achievable Rates and Low-Complexity Encoding of Posterior Matching for the BSC
Amaael Antonini, Rita Gimelshein, Richard Wesel
Horstein, Burnashev, Shayevitz and Feder, Naghshvar et al. and others have studied sequential transmission of a K-bit message over the binary symmetric channel (BSC) with full, noi…
Design, Performance, and Complexity of CRC-Aided List Decoding of Convolutional and Polar Codes for Short Messages
Jacob King, Hanwen Yao, William Ryan +1
Motivated by the need to communicate short control messages in 5G and beyond, this paper carefully designs codes for cyclic redundancy check (CRC)-aided list decoding of tail-bitin…
