Network-coded cooperation algorithm for multiple source - multiple relay topologies in cellular networks

This paper analyzes the performance provided on the uplink connection by a cooperative cluster, composed of user terminals and relays, which employ a XOR-based network coding algorithm. The paper presents the construction of the graphs that describe the operation of the algorithm within the selected topology. It then provides a theoretical analysis of the performance ensured by this algorithm in terms of the outage probability. The Block Error Rate (BLER) performance of the user terminals involved in cooperation are also evaluated for two cooperation topologies characterized by different cooperation graphs.
