Performance evaluation for scattering MIMO channel models

Using a multiple-input multiple-output (MIMO) outdoor wireless fading channel model previously introduced by the authors, we study the impact of physical propagation parameters in a full scattering scenario on outage capacity and ergodic capacity. In particular, introducing the concept of scatterer-to-scatterer (STS) rank, we show that a MIMO channel with correlated inputs (or outputs) but with full STS rank yields better performance from an outage capacity point-of-view than a channel with i.i.d. inputs and outputs and low STS rank.
