摘要:
Methods and systems for doped rateless retransmission include receiving ratelessly coded symbols. An attempt is made to decode the coded symbols using a processor by creating an associated code graph that represents the structure of the rateless code used by the symbols. If the decoding attempt fails, an input node is selected from the code graph using a metric that gauges the number and degree of connections to the input node based on the code graph structure. The selected input node is then requested for retransmission of the selected input node by a feedback channel.
