  abstract={The concept of Virtual Antenna Array (VAA) is a promising approach to apply MIMO concepts in relaying systems. In order to fulfill a given Quality-of-Service (QoS) requirement while reducing the power consumption of the entire system, efficient resource allocation strategies have to be developed. The optimum power allocation solution corresponds to a convex optimization problem. To achieve an analytical solution, the approximative approach IAPA (Improved Approximative Power Allocation) has been proposed by the author. Within this paper this closed-form solution is further analyzed and analytical expressions for the power allocation in case of symmetric relaying networks are derived. Thereby, an approach for analyzing and optimizing different multi-hop scenarios is developed.
