Combined Fountain Code with Network Coding in Cooperative Communication

In this paper, we will investigate the block error rate (BLER) performance in cooperative communication, through combining fountain code with network coding. Contrast to the fixed-rate code, the rate of fountain code is not determined in advance, since that varies according to the instant channel state information. Under the error-free channel condition, network coding can get the maximum possible rate through coding at the correlative nodes not just store-and-forward. Based on this, the error-tolerant coding scheme is proposed by means of integrating fountain code with network coding in cooperative communication. Simulation results show that the proposed scheme can obtain the lower block error rate (BLER), compared with detect and forward scheme.
