Abstract

The invention discloses an accurate positioning and automatic optimization method for an atmospheric waveguide, comprising: detecting a suspected interference source for a time domain feature and a frequency domain feature of an atmospheric waveguide interference to obtain a suspected interference source eNodeBID of a plurality of suspected interference source cells; performing feature coding on the latter N bits of the suspected interference source eNodeBID to obtain a feature coding sequence; transmitting an electromagnetic wave signal including the feature code sequence to the interfered cell on the last two symbols of the DWPTS field by the plurality of suspected interference source cells; obtaining M suspected interference sources eNodeBID with the strongest interference according tothe intensity of the electromagnetic wave signal received by the interfered cell, and decoding the feature coding sequence corresponding to the M suspected interference sources eNodeBID with the strongest interference to obtain the actual interference source eNodeBID and its corresponding actual interference cell. The invention has the advantages of high positioning accuracy of the atmospheric waveguide and fast optimization speed.

Description

technical field [0001] The invention belongs to the field of mobile communication networks, and more specifically relates to a precise positioning and automatic optimization method of an atmospheric waveguide. Background technique [0002] The electromagnetic waves propagating in the atmospheric boundary layer, especially the near-surface layer, are affected by the refraction of the atmosphere, and their propagation paths are bent to the ground. When the curvature exceeds the curvature of the earth's surface, atmospheric waveguide propagation will occur. The atmospheric waveguide phenomenon can cause LTE wireless signals to propagate over long distances. When the propagation distance exceeds the protection distance of the uplink and downlink guard slots (GP) of the LTE system, it will cause the remote LTE wireless signals to interfere with the local LTE wireless signals. [0003] At present, there are three major difficulties in network planning and network optimization of 4...
