A method for analyzing interference relationship between signals based on multi-dimensional interference space model

Abstract

The invention discloses an analysis method for interference relation among signals based on a multidimensional interference space model. The method comprises the steps: firstly determining a plurality of characteristic parameters of an interference signal in a wireless signal domain, generating a corresponding interference model based on the characteristic parameters, and determining a to-be-analyzed interference signal vector and a reference signal characteristic vector; determining a displacement vector (shown in the description) of the interference signal characteristic vector relative to the reference signal characteristic vector, calculating the projection of the displacement vector in an interference space relative to a coordinate axis in a certain dimension, determining the interference state S of the interference signal relative to the reference signal, and further obtaining the interference degree G of the interference signal relative to the reference signal under the condition of interference forming. The method is simple, is convenient to operate, solves a problem of interference judgment and analysis of a wireless communication system better, and facilitates the research and implementation of interference management.
