This thesis characterizes in an experimental way the MIMO channel behavior in different scenarios, including the evaluation of the channel performance dependency with the type of scenario and different propagation conditions. In order to facilitate the development of future systems with multiple antennas in these scenarios, simple and efficient SISO and MIMO channel models are presented. The analysis of the 2?2 MIMO channel has been based on several measurement campaigns carried out in different outdoor, indoor and mixed environments. Two fundamental aspects are studied: the spatial correlation and the channel capacity. The analysis is completed with the development of a method to model the radio channel based on tapped delay lines. Using this method, simple and efficient SISO and MIMO channel models of indoor, outdoor and mixed scenarios have been obtained. In this way this work contributes to the development of new wireless communication systems and to facilitate the simulation of MIMO systems by means of the new proposed models.
