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…
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…
Neural-Network-Optimized Degree-Specific Weights for LDPC MinSum Decoding
Linfang Wang, Sean Chen, Jonathan Nguyen +2
Neural Normalized MinSum (N-NMS) decoding delivers better frame error rate (FER) performance on linear block codes than conventional normalized MinSum (NMS) by assigning dynamic mu…
Finite-Support Capacity-Approaching Distributions for AWGN Channels
Derek Xiao, Linfang Wang, Richard D. Wesel
In this paper, the Dynamic-Assignment Blahut-Arimoto (DAB) algorithm identifies finite-support probability mass functions (PMFs) with small cardinality that achieve capacity for am…
An Efficient Algorithm for Designing Optimal CRCs for Tail-Biting Convolutional Codes
Hengjie Yang, Linfang Wang, Vincent Lau +1
Cyclic redundancy check (CRC) codes combined with convolutional codes yield a powerful concatenated code that can be efficiently decoded using list decoding. To help design such sy…
