The Application of Network Coding in Wireless Communication Networks

As one of the effective methods to approach the network capacity, the network coding technique has received wide attention in the wireless networks. In wireless relay networks, message from several source nodes can be relayed simultaneously via the network coding technique. The three typical application schemes, including belief propagation algorithm over a noisy relay to complete network coding, complex field network coding and joint network-channel coding, can achieve higher throughput and full diversity gain. Compared with conventional cooperative diversity schemes, multi-user cooperation through network coding can attain higher diversity gain and lower symbol error probability.
