Abstract

The invention discloses a simplification order reduction method for a Volterra series behavior model. The method comprises steps that, a general Volterra series behavior model in a discrete mode is established, unknown Volterra nucleuses are simplified according to physical characteristics of a to-be-described circuit, and Volterra series interception is further carried out; the Volterra nucleuses at each order are trimmed by employing a preset trimming method; input signals are recombined according to the trimmed Volterra nucleuses, and an input signal matrix is established; a simplified Volterra series behavior model is acquired through identification by utilizing a preset identification method. Through the method, a problem of curse of dimensionality existing in a general Volterra series behavior model is solved, so the general Volterra series behavior model can be applied to strong non-linear and memory length nonlinear circuit modeling, and application to system-grade electromagnetic compatibility simulation of a nonlinear circuit is convenient.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility, in particular to a simplified order reduction method for a Volterra series behavior model. Background technique [0002] The behavioral model is a mathematical model that describes the input and output behavior characteristics of the circuit. It can ignore the parameters and functions of internal transistor-level components and only rely on the input and output data of the circuit or system, making it possible to simulate electronic systems that are originally complex and have a large number of unsolvable problems. , improving the analysis efficiency. The special status of the nonlinear problem in the electromagnetic compatibility analysis makes the nonlinear behavior model become a research hotspot. Especially in the fields of wireless communication systems, navigation control, etc., the transmitting equipment will use a large number of nonlinear devices and strongly nonli...
