A Generalization Belief Propagation Decoding Algorithm for Polar Codes Based on Particle Swarm Optimization
We propose a generalization belief propagation (BP) decoding algorithm based on particle swarm optimization (PSO) to improve the performance of the polar codes. Through the analysis of the existing BP decoding algorithm, we first introduce a probability modifying factor to each node of the BP decode...
