| 摘 要： | 针对切比雪夫不等式标签数估算方法运算量较大的问题,提出粗精二次搜索RFID标签数动态估算方法(CFDSE),基于由粗至精搜索思想,第一次搜索用加减运算消除平方、开方运算,同时减少第二次搜索范围,可使第二次搜索范围减少约90%。第二次搜索采用切比雪夫不等式估算方法,提高估算准确度。仿真实验表明:CFDSE估算误差小于5%,估算时间比切比雪夫不等式法减少约54%。

| Abstract: | According to the large computation of Chebyshev inequality-based tag estimation method, the dynamic coarse-fine double searching-based tag estimation method （CFDSE） was proposed. Based on the idea of coarse-to-fine search, the first search eliminates square, square root with addition and subtraction, while reducing the second search range. The second search range can be reduced by about 90%. The second search estimation method using Chebyshev inequality to improve the estimation accuracy. Simulation results show that the CFDSE estimation error is less than 5%, the estimation time of about 54% less than the Chebyshev inequality method. |
