Title :
High quality end-to-end-link performance
Abstract :
In this article, an adaptive distributed MIMO multihop network was presented, and the e2e outage probability was derived as the QoS parameter. The task of assigning the physical resources transmit power and the time to reduce the total transmit power while meeting a given QoS constraint was introduced and solved by means of common convex optimization tools. As shown by numerical investigations, the adaptive multihop scheme outperforms the direct transmission and the nonadaptive multihop scheme significantly. Furthermore, a joint optimization of power and time (or bandwidth) is favorable for systems with equal link strength.
