Finding Mimo: a Proposed Model for Incorporating Multiple Input, Multiple Output Technology into Software Defined Radios
نویسنده
چکیده
Multiple Input, Multiple Output (MIMO) technology offers the potential for a significant increase in capacity and performance within a given bandwidth and power budget. However, these benefits must be weighed against the cost of the multiple RF front ends and additional processing necessary in supporting MIMO systems. The creation of a cost effective MIMO system can be facilitated through the use of software defined radio technology. This technology allows systems to be fielded today supporting contemporary waveforms/air interface standards, with MIMO technology added as a future upgrade as the technology matures. A key enabling technology in supporting MIMO in the proposed SDR architecture is the use of a switched-fabric interconnect, such as RapidIO. RapidIO can be utilized to support the dedicate processing model inherent in traditional transceiver designs, and allows the amalgamation of received signals from each antenna into common space-time processing elements for future MIMO applications.
