Abstract
We consider a wireless ad hoc network with single antenna nodes under a two-hop relay traffic pattern. All source-destination pairs communicate concurrently on the same physical channel with the assistance of relay nodes. The gains of the amplify-and-forward relays are assigned such that the interference between different source-destination links is ed [A Wittneben and B. Rankov, Sept. 2004]. This essentially realizes a distributed spatial multiplexing gain with single antenna nodes. The main contribution of this paper is the performance evaluation of this approach on the basis of multihop/multinode channel measurements at 5.25 GHz. We provide comprehensive results on the sum rate supported by multiuser zero forcing (ZF) in relaying and linear distributed antenna systems in an indoor propagation scenario.
