Abstract :
In Wireless 1394, hub station is a device that manages the whole Wireless 1394 home network. Also, hub station plays the role of ad-hoc repeater while the direct communications of leaf stations are obstructed. Multiple-element antenna systems are considered for the hub station. We study the channel capacity when using a multiple-element antenna MIMO architecture for Wireless 1394. We analyse the dependence of the channel capacity on the actual indoor propagation environment. A new geometrical-physical-based channel model including the NAZU (Nakagawa-Arita-Zhang-Udagawa) scattering coefficient is proposed The relation of the POCA (Polydorou-Capsalis) distribution with the MIMO system´s capacity and multipath richness is investigated. It is found that this capacity is limited by the number of significant indoor scatterers
