Network Coding in Relay-Based Networks
Since its inception in information theory, network coding has attracted a significant amount of research attention in recent years. Shortly after theoretical explorations in wired networks, the use of network coding in wireless networks towards improving throughput has been widely recognized. In this chapter, the authors present a survey of recent advances in relay-based cellular networks with network coding. The authors begin with an introduction of network coding theory with a focus on wireless networks. They discuss various network coded cooperation schemes that apply network coding on digital bits of packets or channel codes, in terms of, for example, outage probability and diversity-multiplexing tradeoff.
