Problems solved by technology

[0003] With the convening of WRC15, more and more high-band spectrum needs to be monitored and processed, and many low-band resources need to be re-monitored because they are not fully utilized. Many of the processing software are cumbersome to operate and the presentation method is not very intuitive, which undoubtedly increases the workload of the staff

Embodiment Construction

[0020] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0021] Such as figure 1 It is the processing flow chart of the present invention, which is divided into 4 modules. The data module is used to find the frequency band data preset in the machine, and open it in the software. According to the original data address and the preset frequency band information, the original The file name of the data and call the data in the program; the function of the judgment module is to compare the field strength value in the original data with the preset threshold value to obtain a judgment matrix; the function of the calculation module is to The sampling points corresponding to each frequency point are weighted and averaged to obtain a one-dimensional judgment value array of several frequency points, and the one-dimensional array is arranged into a two-dimensional array according to the order of the frequency points; the function of the...

Abstract

The invention discloses a method for processing spectrum occupancy. The method comprises the following steps: obtaining original data to be processed, and comparing the obtained original data with a threshold to obtain a judgment matrix; processing the data of each frequency point according to a preset time interval to obtain a one-dimensional array; and sequentially processing each frequency point in a frequency band, and combining a series of obtained one-dimensional arrays into a two-dimensional array. The invention further discloses software developed according to the method and based on LabVIEW, and the obtained two-dimensional array is displayed by an intensity graph. By adopting the method disclosed by the invention, a user can observe the change of a spectrum with time more stereoscopically and intuitively.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to software for processing frequency spectrum occupancy. technical background [0002] Radio spectrum resources are important non-renewable resources, and the effective use of spectrum is one of the important factors that should be considered in spectrum management. Spectrum occupancy is the embodiment of effective use of spectrum. The measurement results of spectrum occupancy can not only provide spectrum managers with information about the actual use of spectrum, which is convenient for spectrum managers to assign frequencies, but also provide spectrum usage trends for frequency authorities. Information. Spectrum occupancy measurement is an important part of daily radio spectrum monitoring. [0003] With the convening of WRC15, more and more high-band spectrum needs to be monitored and processed, and many low-band resources need to be re-monitored because they are not full...
