Abstract

The invention discloses a monitoring point layout optimization method for radio environment monitoring. The method comprises the following steps: discriminating areas, where points cannot be distributed, and areas, where points can be distributed, in a target area, discretizing a boundary of the target area and boundaries of the areas, where the points cannot be distributed, in the target area, setting fixed point charges for discrete points, randomly arranging monitoring points in the areas, where the points can be distributed, in the target area, setting free point charges for the monitoring points, adjusting positions of the monitoring points, analyzing forced conditions of the free point charges, and, when the free point charges of the monitoring points are at a force balance state, determining positions of the current free point charges as the best monitoring point positions. Through the optimization method put forward by the invention, the monitoring points can be rationally distributed in the areas where the points can be distributed and can also avoid the areas where the points cannot be distributed.

Description

technical field [0001] The invention relates to the technical field of radio environment monitoring, in particular to a monitoring point layout optimization method for radio environment monitoring. Background technique [0002] The rapid development of radio communication technology has led to a sharp increase in the demand for wireless spectrum resources on the one hand, and the shortage of spectrum resources has become one of the bottlenecks in the future development of radio technology. On the other hand, with the access of a large number of radio devices, the radio environment becomes more and more complicated, and there are a lot of illegal frequency usage phenomena. To solve the problem of limited spectrum resources, efficient spectrum utilization technologies such as cognitive radio are proposed in the prior art. The core idea of ​​cognitive radio technology is to use the radio environment monitoring system to detect the idle frequency of the primary user in time, an...
