摘要： Loop gain normalization is employed in adaptive filters to control weighting of the filter characteristic updates in order to converge properly to a desired filter characteristic. Filter stability and rapid high quality convergence is realized for a variety of received or inputted signals by employing both long term and fast attack estimates of a prescribed input signal characteristic to normalize the update gain. In one embodiment, both long term and fast attack input signal power estimates are generated and one of the two estimate values is selected to normalize the update gain. Specifically, the fast attack estimate is modified by a predetermined value and, then, the larger of the long term estimate and modified fast attack estimate is selected to normalize the update gain.

摘要： In adaptive filters, under certain incoming signal conditions the tap coefficients tend to drift toward relatively large values. This condition has been countered by introducing so-called leakage into the tap coefficients which tends to drive them toward zero. Introduction of leakage is desirable under certain incoming signal conditions and not others. Indeed, during intervals that partial band energy, e.g., single frequency tones, multifrequency tones and the like, is incoming to the filter there is a need to introduce a relatively large leakage value into the tap coefficients. However, during intervals that whole band energy, e.g., speech or noise, is incoming to the filter no leak is desired or needed. This is realized by detecting intervals when partial band energy is incoming to the filter and controllably increasing the leakage value during those intervals.
摘要翻译：在自适应滤波器中，在某些输入信号条件下，抽头系数往往偏向较大的值。这种情况已经通过将所谓的泄漏引入到趋向于将它们驱动到零的抽头系数来抵消。在某些输入信号条件下，不需要引入泄漏，而不是其他情况。实际上，在部分频带能量（例如单频率音调，多频音调等）进入滤波器的间隔期间，需要在抽头系数中引入相对较大的泄漏值。然而，在整个频带能量（例如语音或噪声）进入滤波器的间隔期间，不需要或需要泄漏。这是通过检测当部分波段能量进入滤波器时的间隔，并且可控地增加那些间隔期间的泄漏值来实现的。
