An analytical study of network coding in the presence of real-time messages
(2010)With network coding, two data packets are transformed into one by a simple XOR-operation. The transformed packet is transmitted and each original packet can be retrieved at its destination node through a similar XOR-operation. ... -
Capacity-achieving encoding for the broadcast erasure channel with multiple users
(2011)We consider the N-user memoryless broadcast erasure channel with N unicast sessions (one for each user) where receiver feedback is sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ... -
