Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques face a decrease in detection accuracy when a signal to be detected exists at the boundary of divided spectrum images.
Innovation Solution
An information processing apparatus that divides a spectrum image into multiple images, detects specific signals in each image, and integrates signals across adjacent images based on coordinate and power level analysis to enhance detection accuracy.

1Productivity
If spectrum data is divided into multiple divided areas for parallel processing, then processing speed is improved, but detection accuracy decreases when signals exist at boundaries of divided images
Solution Approach 1:
The spectrum image is divided into multiple divided spectrum images for parallel processing, improving processing speed while maintaining the ability to detect signals through coordinate integration across divided regions
Solution Approach 2:
Detection results from multiple divided spectrum images are integrated by combining coordinate information and determining signal continuity across boundaries, resolving the accuracy loss caused by division and enabling complete signal detection even when signals span multiple divided regions

AI summary
To enable appropriate detection even in a case where a signal to be detected exists across a plurality of divided images. Provided is an information processing apparatus includes: a division unit that divides a spectrum image of a received radio signal into a plurality of divided spectrum images including a first divided spectrum image and a second divided spectrum image; a detection unit that detects a first specific range including a first specific signal in the first divided spectrum image and a second specific range including a second specific signal in the second divided spectrum image; and an output unit that, in a case where the first specific signal and the second specific signal are included in a specific signal across the first divided spectrum image and the second divided spectrum image, outputs information based on the specific signal.
