A Nonlinear Signal Processor’s Design Framework and Implementing Means

Nonlinearities are often encountered in the analysis and processing of real signals.The method often used is transforming the signal from nonlinear signal to linear signal by transiting it through a processing system.In this paper,a nonlinear signal processor's design framework and implementing means are given.Its fundamental is letting the signal being processed by a nonlinear filter,and according to mathematics we can prove that the signal after filtering is linear.Moreover,different transform basis and filters can be selected depending on different kinds of signal.
