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…

Reconstruction-Computation-Quantization (RCQ): A Paradigm for Low Bit Width LDPC Decoding
Linfang Wang, Caleb Terrill, Maximilian Stark +7
This paper uses the reconstruction-computation-quantization (RCQ) paradigm to decode low-density parity-check (LDPC) codes. RCQ facilitates dynamic non-uniform quantization to achi…

FPGA Implementations of Layered MinSum LDPC Decoders Using RCQ Message Passing
Caleb Terrill, Linfang Wang, Sean Chen +4
Non-uniform message quantization techniques such as reconstruction-computation-quantization (RCQ) improve error-correction performance and decrease hardware complexity of low-densi…
