模式搅拌混响室中独立样本数实验提取的改进
Refining the Experimental Extraction of the Number of Independent Samples in a Mode-Stirred Reverberation Chamber
摘要：
我们研究了混沌混响室中的独立样本数。当不使用大于相关长度的第一值的索引而是使用通过线性插值获得的值时，可以使其如IEC标准所定义的评估更精确。通过与使用高搅拌器角度分辨率的测量值并置来验证结果。与文献中已知的估计值的比较验证了我们的研究结果。另一种方法使用的传输的参数依赖的局部最大值，以显示在很大的频率范围内的提取的相关长度的适用性。
英文摘要：
We investigate the number of independent samples in a chaotic reverberation chamber. Its evaluation as defined by the IEC standard can be made more precise when using not the index of the first value larger then the correlation length but using the value obtained by a linear interpolation instead. The results are validated by a juxtaposition with values from a measurement using a high stirrer-angle resolution. A comparison with estimates known from the literature validates our findings. An alternative approach using the local maxima of the parametric dependence of the transmission is presented in order to show the applicability of the extracted correlation length over a large range of frequencies.
