Abstract
In our work we study a cooperative system using multiplexing. The key idea of a cooperative system is, that spatially separated stations assist each other to build up a distributed smart antenna and thereby to improve the efficiency of their transmissions. Here, the multiple antenna link will be exploited by multiplexing. In order to evaluate the multiple antenna link, we introduce a system model considering one cooperative station. From this, we present the capacity and some properties of system, which differ form ordinary MIMO systems. Furthermore we derive the optimal amplification factors, which specify the optimal power allocation. Finally we compare the ergodic capacity between simple and cooperative transmission.
