Abstract: A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.

Abstract: Multistage Wiener filters (MWF) represent a component of the MWF as an un-normalized vector of filter coefficients within a finite impulse response (FIR) filter in a manner that avoids reliance on the 2-norm operation of the un-normalized vector of coefficients. The 2-norm operation can be replaced by less expensive operations performed elsewhere in the MWF. Preferably the filter adds only a few additional addition, subtraction and multiplication operations to compensate for the elimination of the square root and the division operations used for the 2-norm operation. As a result, it is possible to eliminate all or nearly all of the square rod and arithmetic division operations of at least some implementations of the MWF.

Abstract translation: 多级维纳滤波器（MWF）以有限脉冲响应（FIR）滤波器中的滤波器系数的非归一化向量作为MWF的分量，以避免依赖于系数的非归一化矢量的2范数运算 。 可以通过在MWF其他地方执行的较廉价的操作来代替2规范操作。 优选地，滤波器仅添加少量附加，减法和乘法运算，以补偿平方根的消除和用于2范数运算的除法运算。 结果，可以消除MWF的至少一些实施方式的所有或几乎所有的方棒和算术分割操作。

Abstract: A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.

Abstract: A system that incorporates the subject disclosure may perform, for example, a method for receiving interference information from each of the plurality of communication devices detecting interference information in a plurality of segments of a radio frequency spectrum, correlating the interference information of the plurality of communication devices to generate correlated information, and identifying a plurality of interferers according to the correlated information. Other embodiments are disclosed.
