Abstract :
A decode-and-forward two-hop relay network exploiting spatial diversity is considered. By considering transmission overheads in detail to exploit spatial diversity, an explicit expression is derived for the average transmission capacity of the relay network, which is a function of the transmission time and coding rate by the source. Some numerical examples based on analysis are provided to demonstrate performance behaviour.
