We develop cooperation methods based on Raptor codes with the assumption that the channels face erasure with specific erasure probabilities and transmitters have no channel state information. ...
A fully coded cooperation (FCC) and a partially coded cooperation (PCC) strategy are developed to maximize the average system throughput. ...
Although Growth codes [25, 28] achieves both good full and partial decoding performance, they require a large number of feedback from the destination; thus not appropriate for the PCC scheme. ...
