Executive Summary

A Generalized Adaptive Network Coding (GANC) scheme is conceived for a multi-user, multi-relay scenario, where the multiple users transmit independent information streams to a common destination with the aid of multiple relays. The proposed GANC scheme is developed from Adaptive Network Coded Cooperation (ANCC), which aims for a high flexibility in order to: allow arbitrary channel coding schemes to serve as the cross-layer network coding regime; provide any arbitrary trade-off between the throughput and reliability by adjusting the ratio of the source nodes and the cooperating relay nodes. Furthermore, the authors incorporate the proposed GANC scheme in a novel Successive Relaying Aided Network (SRAN) in order to recover the typical 50% half-duplex relaying-induced throughput loss.
