We present a novel channel model for a two-hop decentralized wireless relay network (DWRN), where the relays operate in a completely distributive fashion. The model is based on an analogous approach to the conventional description methods for wideband directional multipath channels. Specifically, the notion of information azimuth-delay spectrum (IADS) is devised. This definition, parallel to the widely-used power azimuth-delay spectrum (PADS) for physical multipath channels, represents a compact description of virtual DWRN channels. The proposed approach is also applied to a circular random network (CRN) with uniformly-distributed relay nodes. Finally, numerical examples are used to demonstrate the usefulness of the suggested channel description method.
