Integrating dual antennas into the wimedia UWB framework for WPANs

Multiple Input Multiple Output (MIMO) technology is a well-established antennae technology that can not only increase system capacity, but can also extend the link coverage area for wireless communication systems. In this paper, MIMO technology has been applied to Wireless Personal Area Networks (WPANs) that operate in the license free Ultra Wide Band (UWB) spectrum. A dual antenna configuration applying Dual Circular DC32-QAM (Quadrature Amplitude Modulation) is proposed for indoor wireless systems that can improve the transmitting rate and coverage area for range demanding applications. Simulation results in terms of a performance analysis of bit error rates and throughput are then presented, and shown that significant improvements in the proposed model over traditional systems can be obtained.
