Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, accurately analyzing the channel environment is challenging due to the influence of objects not visible in two-dimensional image information, especially with mmWave signals, which require more accurate simulation results for network planning.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional image information is used to determine object characteristics, then the analysis process is simple, but objects not appearing in image information cannot be identified
Solution Approach 1:
The patent combines satellite information (providing area information about objects) with image information (providing characteristic information) to create a comprehensive object analysis system. This merging allows the system to identify objects that would be invisible in two-dimensional images alone, such as underground pipelines or structures obscured by buildings, while maintaining practical analytical capabilities
Solution Approach 2:
The patent transitions from two-dimensional image information to three-dimensional spatial understanding by incorporating satellite-derived area information. This dimensional enhancement enables the system to detect and analyze objects in vertical or hidden dimensions that cannot be captured by traditional 2D imaging, thereby improving object identification accuracy without excessive complexity
2Measurement precision
If satellite information and image information are combined to identify all objects, then the accuracy of channel analysis is improved, but the complexity of the analysis system increases
Solution Approach 1:
The patent divides the analysis system into distinct functional modules: a satellite information processing unit that extracts area information, an image information processing unit that extracts characteristic information, and a synthesis unit that combines them. This segmentation allows each module to specialize in specific tasks, improving overall accuracy while managing system complexity through modular design
Solution Approach 2:
The patent creates a multi-functional analysis system that can handle both satellite-derived area information and image-derived characteristic information within a unified framework. This universal approach allows the same system to analyze various object types (buildings, vegetation, underground structures) using different information sources, improving channel analysis accuracy across diverse scenarios without requiring separate specialized systems
