简介:在收音机频率鉴定(RFID)系统,backscattered信号对干扰小、容易。RFID标签identi的表演?在干扰情形的阳离子在无差错的情形与那相比被降级。在这份报纸,一个新奇Mahalanobis距离估计(MDE)方法被建议联合估计标签和包错误率的数字(每)。当干扰正在损害观察信息时,MDE方法是由于它完成一个稳定的评价的能力有弹性的错误。建议方法由在观察结果之中考虑所有信息和关联在存在方法上完成显著地提高的精确性。MDE方法基于观察信息的有效decorrelation和分类改进估计表演。而且,PER估计的表演在理论并且通过模拟被分析。它能从分析被结束估计了每不偏、围住变化。模拟证明建议估计以精确性和稳定性超过以前的建议,它在干扰情形为申请使它合适。
