Throughput of distributed-MIMO multi-stage communication networks over non-ergodic channels

Distributed-MIMO multi-stage communication networks were shown to yield superior performance over traditional networks which is due to the facilitated MIMO channels as well as gains obtained from relaying. Of major concern for such networks is a proper allocation of resources to each terminal so as to maximise end-to-end throughput. In contrast to ergodic channels, the optimum end-to-end throughput over non-ergodic channels is dominated by a fairly intricate relation between desired rates and associated outage probabilities. The contribution of this paper is the derivation of explicit near-optimum resource allocation strategies, the precision and performance of which is also analysed.
