A Novel Variable-Order Threshold Serial Belief Propagation-Based Decoding Algorithm for LT Codes

A Novel Variable-Order Threshold Serial Belief Propagation-Based Decoding Algorithm for LT Codes

The belief propagation (BP) algorithm is a widely adopted iterative decoding method for Luby transform (LT) codes. However, the conventional log-likelihood ratio BP (LLR-BP) decoder exhibits inherent limitations in additive white Gaussian noise (AWGN) channels. These limitations include high computa...
