Measurement Data Histograms for Historical Interference Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing measurement data, such as max-hold detection and persistent waterfall diagrams, fail to provide historical information, making it difficult to identify interference and perform real-time comparisons between multiple antennas or receivers for time alignment and base-station position estimation.
Innovation Solution
A method and system that combines two-dimensional histograms with persistent waterfall diagrams, allowing for the integration of past measurements as time-variant histograms, providing historical data and enabling real-time comparisons by associating each waterfall line with an individual histogram.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If persistent waterfall diagrams are used to display historical measurement data, then historical information is provided, but interference detection and comparison between multiple antennas becomes difficult due to superimposed traces
Solution Approach 1:
The patent segments the superimposed measurement traces by assigning each antenna or receiver a separate waterfall line in the diagram. Instead of overlaying all historical data in a single trace, the system divides the visualization into distinct lines, each representing individual measurement histories. This segmentation allows operators to clearly distinguish between different sources and time periods, enabling effective interference detection while preserving historical information.
2Ease of operation
If max-hold detection technique is used to display current measurements, then current values are visible, but no historical information about measurements is provided
Solution Approach 1:
The patent merges the advantages of max-hold detection with persistent waterfall diagrams by integrating both techniques into a single system. The max-hold detection provides clear visibility of current maximum and minimum values, while the persistent waterfall component simultaneously displays historical measurement data as time-variant histograms. This combination ensures that operators have access to both real-time extremes and historical context without sacrificing either capability.
3Loss of information
If multiple measurement traces are superimposed to show history, then historical data is visualized, but storage requirements increase and data comparison becomes difficult
Solution Approach 1:
The patent extracts only the essential characteristics from historical measurement data by generating time-variant histograms that summarize measurement distributions over specific periods. Instead of storing and displaying every individual measurement point, the system extracts key statistical features and presents them in a condensed histogram format. This extraction approach reduces storage requirements and simplifies data processing while maintaining the ability to visualize historical trends and perform comparisons.

AI summary
The present disclosure concerns a method of processing measurement data. The method includes gathering measurement data by a measurement component, processing the measurement data by the measurement component, thereby producing at least one two-dimensional histogram of a measurement quantity depending on a variable for at least one period of time, forwarding, by the measurement component, the at least one two-dimensional histogram to a processing component, and processing, by the processing component, the at least one two-dimensional histogram received from the measurement component, thereby generating data associated with at least one histogram and data associated with a waterfall diagram having several waterfall lines, wherein each of the several waterfall lines is associated with an individual histogram. Further, the present disclosure concerns a system for processing measurement data.
