Factor Graph Approach for Decoding Reed Muller Codes
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
Factor graphs basically work on the idea of marginalization i.e. sub-dividing a larger function into a number of smaller functions whose contribution to the solution of the problem are considered accordingly. This paper uses Forney factor graph, which is a bipartite graph that models a system into function nodes and variable nodes. The messages are passed to and fro the two sets of nodes via specific message update rules chosen beforehand and the phenomena may be based on sum product or the max product algorithm. The algorithm converges to a decoded output after either a fixed number of iterations or is made to terminate after a threshold is achieved.
