Radio Wave Threshold Determination via Intersection Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators, especially inexperienced ones, face difficulties in distinguishing between effective frequencies and noise in received radio waves due to the variability of suitable threshold values based on conditions like location and season, making it challenging to determine appropriate threshold values.
Innovation Solution
A wireless communication apparatus and analysis method that determine a threshold value for distinguishing noise from received radio waves by calculating the number of intersections between a variation curve of radio wave intensity and a given intensity line, allowing for automated threshold determination without relying on operator expertise.

Engineering Contradiction Analysis
1Measurement precision
If an operator determines the threshold value based on experience and skill, then the threshold determination can be adapted to different conditions, but inexperienced operators cannot accurately distinguish between effective frequencies and noise
Solution Approach 1:
The system performs self-diagnosis by automatically determining the threshold value through analyzing the number of intersections between the variation curve and reference lines, eliminating the need for operator expertise in threshold determination
Solution Approach 2:
The system changes the parameter determination approach from experience-based subjective judgment to objective calculation based on the number of intersections, transforming the threshold value into a quantifiable parameter that can be automatically determined
2Ease of operation
If a fixed threshold value is used for distinguishing noise, then the operation is simplified, but the threshold becomes inappropriate for different places and seasons
Solution Approach 1:
The threshold value is made dynamic by automatically adjusting it based on the analyzed number of intersections, allowing the system to adapt to different environmental conditions while maintaining simple operation through automated adjustment

AI summary
Provided are a wireless communication apparatus, an analysis apparatus, an analysis method and a non-transitory computer readable medium on which a program has been stored, in which a threshold value to be used for determining whether received radio waves are noise can be determined independently of an operator's capability. A threshold value is determined, on the basis of a number of intersections between a variation curve of radio wave intensity relative to the frequencies of the radio waves received by a receiver and a first line indicating a given radio wave intensity, a threshold value of radio wave intensity to be used for determining whether the received radio waves are noise.
