Performance Of Distributed Multi-Stage Virtual Mimo Systems With Random Position Of Ancillary Nodes

The performance of two-hop decode-and-forward virtual multiple-input-multiple-output systems with random location of nodes, is investigated. We suppose that source, relay and destination nodes create clusters with ancillary nodes which are spatially distributed according to a Poisson point process. Random fluctuations are accounted for in the channel model which considers both slow and fast fading. By assuming that the application requires a minimum amount of rate, we evaluate the system performance in terms of cumulative density function of the required signal-to-noise ratio. The use of orthogonal space-time-block codes is also considered and the role played by connectivity parameters is investigated.
