Dynamic relay and region selection for PB/MC-CDMA distributed cooperative communication system

In this paper, we propose a new distributed cooperative communication scheme based on partial block MC-CDMA (PB/MC-CDMA) system to achieve optimal performance. As known, the performance of distributed cooperative communication has a relationship with the selection of relay node and relay region. Considering these two factors, a time interval is added and the relay region is defined by simulation. During the time interval, relay node is chosen according to the rule of maximum frequency diversity, different region using different transmission and the performance restricted of relay nodes are all assurances of good performance. The simulation results show that this transmission method can get a better performance without any additional transmission power.
