Frequency spectrum monitoring data structured representation method, and data processing method and compression method

A compression processing method for spectrum monitoring data of multiple stations, characterized in that, comprising the following steps of:

• S1:
• structured representation of spectrum monitoring data of single station:
• according to a unified monitoring frequency bandwidth, monitoring a sampling interval of time dimension and a sampling interval of frequency dimension, completing discretization of the frequency dimension and discretization of the time dimension of the monitoring data in a given time period at a given time and a given bandwidth, expressing the spectrum monitoring data of the given monitoring time period and the frequency bandwidth as a spectrum matrix;
• S2:
• structured representation of spectrum monitoring data of multiple stations:
• arranging all the spectrum matrices obtained by the multiple stations in a given area into a spectrum matrix body according to specific rules of the station position;
• S3:
• Gray-scale processing of spectrum monitoring data:
• selecting a dimension from the three dimensions of the spectrum matrix body, where the spectrum matrix body can be regarded as an arrangement of a series of matrices in the selected dimension, transforming each of the matrices into a grayscale image by gray-scale processing such that the spectrum matrix body can be regarded as a piece of video data;
• S4:
• Utilization of video compression method to compress monitoring data:
• for the monitoring data of multiple stations in a given area, there is a large amount of redundant information in the dimensions of time, frequency, and position, compressing the video data corresponding to the spectrum matrix body by using traditional video compression standards.

A compression processing method for spectrum monitoring data of multiple stations, characterized in that, comprising:

• S1:
• arrange the two-dimensional spectrum matrices of multiple stations to form a three-dimensional spectrum matrix body according to the mutual relationship between the positions of the stations, wherein the two-dimensional spectrum matrix of each station is formed by the discretization of the spectrum monitoring data of the station in the time and frequency dimensions;
• S2:
• Select one dimension from the three dimensions of the three-dimensional frequency spectrum matrix body, carrying out grayscale processing of each matrix to convert to grayscale image;
• S3:
• compress the spectrum monitoring data in the selected dimension by using video compression method.
