An Interleaved Spectrum Allocation Method

Abstract

The invention discloses a method for staggered frequency spectrum allocation. The method comprises the following steps: determining available frequency points of each device according to artificially prohibited frequency points, environmental constraints and communication constraints; performing digital representation on frequency point conflicts, and constructing equipment The interference matrix between them and the corresponding frequency point interference pair; sort the devices to be allocated frequency points according to the priority order of the devices; staggered frequency point allocation, comprehensively considering the priority of the device, the available frequency points of the device, and the frequency points between devices According to the level of interference, frequency points are assigned in turn according to the priority of the equipment and unusable frequency points are excluded. While allocating frequency points, the interference matrix is ​​continuously updated until the frequency points of all devices are allocated or excluded. The present invention proposes an interleaved frequency spectrum allocation method, which ensures that each electronic equipment obtains usable frequency points to the greatest extent while ensuring that the frequencies used by electronic equipment do not interfere with each other, and the distribution of frequency points in the working frequency band of the electronic equipment is balanced.

Description

technical field [0001] The invention relates to electromagnetic compatibility analysis and spectrum technology, in particular to a staggered spectrum allocation method. Background technique [0002] Electromagnetic spectrum resources are increasingly scarce. For areas where a large number of electronic devices are distributed, the allocation of spectrum resources between electronic devices is a key issue. The electromagnetic spectrum of electronic equipment usually occupies a certain spectrum width. The more types and quantities of high-power electronic equipment and the wider the spectrum occupation, the more serious the electromagnetic spectrum conflict in the region, and the higher the requirements for spectrum resource allocation. Therefore, when many high-power electronic devices are distributed in a certain area and their relative positions change in real time, it is necessary to focus on how to quickly allocate electromagnetic spectrum resources for electronic devices...

Problems solved by technology

This method is not only inefficient, but also with the increasing complexity of the electromagnetic environment and the increasing number of frequency-using devices, the workload increases exponentially and is prone to errors. Moreover, the staggered interval of frequency points cannot be accurately estimated, resulting in the inability of electromagnetic spectrum resources. fully utilized
