摘要

在一些信号处理应用中，可能需要由扬声器和麦克风组成的信号路径的离散时间模型。例如，该模型可用于选择自适应滤波器的系数数。本文从精度和计算复杂度两个方面比较了获得该模型的不同方法。并给出了不同方法应用的实验结果。

Measuring acoustic responses with maximum-length sequences

In several signal processing applications, a discrete-time model of a signal path which comprises of a loudspeaker and a microphone may be desired. For instance, the model can be used to choose the number of coefficients of an adaptive filter. In this work, different methods of obtaining such a model are compared on the basis of their precision and computational complexity. Experimental results from the application of the different methods are also presented.
