Executive Summary

Multiple-Input Multiple-Output (MIMO) mobile ad hoc networks have been receiving increased attention in both commercial and military applications. Just as in cellular networks, MIMO technologies can benefit ad hoc networks by providing the diversity and capacity advantages as well as the spatial degree of freedom in designing the Media Access Control (MAC) protocol. However, one fundamental issue of MIMO mobile ad hoc networks is how to accurately model the impact of spatial/temporal channel correlation in the mobile-to-mobile communications environment. In such a channel, Line-Of-Sight (LOS) components and different scattering environments will affect both ergodic capacity and average capacity fading duration of the MIMO system.
