自适应线谱干扰抵消器的性能及其非维纳滤波现象

Performance of the adaptive line canceller and its "non-Wiener" phenomenon

自适应滤波器的性能通常采用维纳滤波器理论来分析，本文指出自适应线谱干扰抵消器不符合经典解的现象。在对权系数的动态分析中，揭示了非维纳滤波效应产生的机理。

It is well known that the performance of adaptive noise canceller is typically analyzed in terms of the Wiener filter theory. In this paper, study on the adaptive line canceller shows a solution that falls outside the scope of the classical theory. Investigation on dynamic behavior of the weights brings forth insight into 'non-Wiener' phenomenon.
