Abstract

A new way to model a CDMA-system applying relaying is proposed in this paper. This method makes it possible to compare directly the performance of relaying. The outage probability, which represents the ability of the users to reach the base Station, is chosen as criteria to compare the system with and without relaying. The model is based on the single mode air interface WCDMA FDD with a two-hop relay. When relaying is applied, the simulation results show that even by using the single mode FDD the uplink capacity is significantly improved by 82%. Also a new relay node selection strategy is proposed and the results show how important it is to choose appropriately the relay node. And finally, different scenarios of relaying are simulated to show when or when it is not better to apply relaying.
