In order to address the ever-increasing demand for capacity in wireless personal area networks (WPANs), the framework associated with the WiMedia ultra-wide band (UWB) standard has been implemented in many WPAN systems. To increase capacity, multiple-input, multiple-output (MIMO) technology is a well-established antenna technology that can not only increase system capacity, but can also extend the link coverage area for wireless communication systems. In this presentation, a review of existing research in the implementation of MIMO into the UWB domain is presented, and a model is proposed for its implementation. Initial simulations in terms of performance analysis of bit error rates and throughput are then presented, and these show the significant improvements that the proposed model can provide.
