Capacity of 1-to-K Broadcast Packet Erasure Channels With Channel Output Feedback

In the last decade, the new network coding concept has emerged, which focuses on achieving the capacity of a communication network. More explicitly, the network-coding-based approaches generally model each hop of a packet-based communication network by a Packet Erasure Channel (PEC) instead of the classic Gaussian channel. Such simple abstraction allows users to explore the information-theoretic capacity of a much larger network with mathematical rigor and also sheds new insights on the network effects of a communication system. One such example is the broadcast channel capacity with message side information.
