低复杂度非线性滤波器
Abstract:
公开了一种处理包括输入变量的输入信号的方法。该方法包括将上述输入变量与一组有序常数进行比较，确定该输入变量在可能的输入范围内的相对位置和使用该输入变量的相对位置确定非线性滤波器的滤波器系数。一种可配置的滤波器包括配置成接收包括输入变量的输入信号的接口，耦合到该接口的、配置成用来处理上述输入信号的非线性滤波器，以及耦合到该非线性滤波器的、配置成确定上述输入变量在可能的输入范围内的相对位置和使用该输入变量的相对位置确定非线性滤波器的滤波器系数的处理器。
Abstract(English):

A method of processing an input signal that includes an input variable is disclosed. The method comprises comparing the input variable to a set of ordered constants, determining the relative locationof the input variable within a range of possible inputs and determining a filter coefficient of a nonlinear filter using the relative location of the input variable. A configurable filter comprises aninterface configured to receive an input signal that includes an input variable, a nonlinear filter coupled to the interface, configured to process the input signal, and a processor coupled to the nonlinear filter, configured to determine the relative location of the input variable within a range of possible inputs and to determine a filter coefficient of the nonlinear filter using the relative location of the input variable.
