In future multiuser wireless systems, the limited system resources have to be extensively reused for serving several users. This results in received interferences at the users which limit the performance of the system. A scenario with several source-destination node pairs communicating unidirectionally through a shared medium is considered. The communication among the nodes is assisted by some relays and takes place in two time slots. The present dissertation focuses on investigating how the relay and the filter coefficients can be smartly adjusted such that the system performance is enhanced.
