In this paper, we propose different practical distributed schemes to solve the rank failure problem in the compute and forward (CMF)-based multi-user multi-relay networks without central coordinator, in ...
Then, as the second scheme, amplify-forward and compute (AFC) is introduced in which the equations are recovered in the destination rather than in the relays. ...
System Model We consider a multi-user multi-relay cooperative network, shown in Fig. 1 [18] , consisting of L users, M relays and one common destination. ...

In this paper, we study the relay selection problem in multi-user, multi-hop relay networks with the objective of minimizing the maximum outage probability across all users. ...
This solution breaks down in the multi-user scenario due to dependence between users. We resolve this challenge using a novel relay aggregation approach. ...
While these approaches provide interesting solutions in single-user networks, work on multi-user relay networks is still limited. ...
