| Abstract(in English) | In this report, we deal with fountain coding scheme in which a sender sends infinitely long coded bits until receivers successfully complete decoding. A fountain code is called universal if for arbitrary C∈(0,1), the code achieve any binary-input memoryless symmetric channels of capacity C. We give a necessary condition that a spatially-coupled Hsu-Anastasopoulos fountain code is universal. We numerically observe that the most efficiently decodable spatially-coupled HA fountain code satisfying the necessary condition achieves the capacity of the binary symmetric channels and binary-input additive white Gaussian noise channels by density evolution. |
