英文摘要
A testing method is investigated for performance evaluation and optimization of radio frequency identification and multi-input multi-output (RFID-MIMO) system based on Cramer- Rao Bounds (CRB). Based on the channel model of RFID-MIMO system, a CRB estimator of antenna azimuth in single antenna multiple tag system is obtained. A simulation on the CRB of different number of tags is made. In this research, we study the relationship between the CRB of multiple tags’ distribution and the reading performance. Moreover, a quantitative index of optimization is proposed by multiple tags analysis. The antenna selection technique of RFIDMIMO system is analyzed. The feasibility of this method is verified by comparing the optimal and the suboptimal antenna selection technique. This study provides an effective reference for the evaluation and optimization of RFID-MIMO system.
