带有无源标签的射频识别系统是物体识别的有力工具。但是，如果要同时识别多个标签，则来自标签的消息可能会发生冲突并相互抵消。因此，为了实现高识别率，必须执行多个读取周期。对于典型的随机防冲突方案，我们展示了如何确定在给定保证水平下执行的最佳读取周期数，从而确定可接受的标签遗漏比率。这产生了用于对象识别的有效过程。我们还给出了关于实现性能的结果。
Radio frequency identification systems with passive tags are powerful tools for object identification. However, if multiple tags are to be identified simultaneously, messages from the tags can collide and cancel each other out. Therefore, multiple read cycles have to be performed in order to achieve a high recognition rate. For a typical stochastic anti-collision scheme, we show how to determine the optimal number of read cycles to perform under a given assurance level determining the acceptable rate of missed tags. This yields an efficient procedure for object identification. We also present results on the performance of an implementation.
