Knowledge-Aided Reweighted Belief Propagation LDPC Decoding using Regular and Irregular Designs
J. Li, R. C. de Lamare
In this paper a new message passing algorithm, which takes advantage of both tree-based re-parameterization and the knowledge of short cycles, is introduced for the purpose of deco…

Locally-Optimized Reweighted Belief Propagation for Decoding LDPC Codes with Finite-Length
J. Li, R. C. de Lamare, H. Wymeersch
In practice, LDPC codes are decoded using message passing methods. These methods offer good performance but tend to converge slowly and sometimes fail to converge and to decode the…
