Wireless communication interference prediction method for atmospheric waveguide

Abstract

The invention discloses a wireless communication interference prediction method for an atmospheric waveguide. The method comprises the following steps: calculating the regional occurrence probabilityof the waveguide by using a statistical method; establishing a relational expression of an electromagnetic wave wavelength, an emission elevation angle and a waveguide parameter when the electromagnetic wave is captured; calculating a disturbing end capture probability and a disturbed end disturbed probability based on a relational expression of an electromagnetic wave wavelength, an emission elevation angle and a waveguide parameter when the electromagnetic wave is captured; and establishing a waveguide interference event prediction model according to an addition principle and a multiplication principle based on the region occurrence probability of each type of waveguide, the disturbing end capture probability and the disturbed end disturbed probability, and predicting the waveguide interference event occurrence probability of the region to be predicted according to the waveguide interference event prediction model. According to the method, the waveguide interference event can be predicted, so that an adversarial means can be adopted in advance, and the quality of wireless communication is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for predicting wireless communication interference caused by an atmospheric waveguide. Background technique [0002] When the gradient dM / dz of the atmospheric correction refractive index M in the vertical direction within a certain spatial range in the atmosphere dM / dz<0 or the gradient dN / dh of the atmospheric refractive index N along the vertical direction of the ground<-0.157N units / m, the atmospheric node called an atmospheric waveguide. Atmospheric waveguide is a special atmospheric structure formed by the abnormal decrease of atmospheric refractive index with height under special weather conditions. This structure makes the curvature of electromagnetic wave to the ground during propagation larger than the curvature of the earth, so that electromagnetic energy can be bound in the Atmospheric waveguide propagation is formed in speci...

Problems solved by technology

[0005] The CoupledOcean / Atmosphere Mesoscale Prediction System (COAMPS), developed by the U.S. Naval Research Laboratory, has been put into operational use to study and predict the height of the evaporation duct and the atmospheric refraction environment, but the system has a large impact on the height of the duct. and intensity descriptions are not accurate enough to predict the probability of waveguide interference communication events well with this system

Moreover, at present, when major communication operators in my country deal with waveguide interference wireless communication incidents, they only take measures passively, and cannot proactively predict waveguide interference communication events, so that they cannot be dealt with in time when waveguide interferes with communication, which will lead to a certain period of time. communication failure

There are currently no published studies that can predict the interference of wireless communications from one area to another by waveguides
