Physical Layer Network Coding for Cooperative Wireless Networks

NetCodMod5G

Network Coding is a new technique for wireless relaying or multi-hop networks in which data received from multiple sources at intermediate nodes is combined and re-coded, instead of being simply selected and forwarded. It has the potential of significantly increasing throughput in multiuser wireless networks: for example it can readily double the capacity of a pair of terminals communicating with one another via a relay. However its application in wireless networks is more complex because of the inherent interference between links, and problems such as fading.

The project will exploit a new approach to physical layer network coding, known as network-coded modulation, to find both the limits on the capacity of this approach, and practical implementations of it. The project also investigates the newly emerged technique, namely, the compute-and-forward or so-called reliable physical-layer network coding, which adopts the structured codes to exploit the linear structure of the channel such that the relay only decodes linear combinations of the codewords transmitted by each user. In particular, some practical design for compute-and-forward is considered, where the algebraic approach is used to find the finite dimensional constellation for the purpose of hardware implementation.
