We investigate a cooperative communications scheme with N relays, where both the transmissions from the source to the relays and from the relays to the destination use fountain codes. Fountain code is more suitable cooperative communication. In order to achieve high-efficiency cooperative communication, when CSI is unknown to the sender, a multi-relay cooperative model is proposed, and LT code apply in it, furthermore, we discussed two transmission modes, error bit rate and the probability density. Simulation results show that: comparing to direct transmission, the scheme have lower bit error rate, as well as a faster decoding speed.
