Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real environment measurements are conducted, then data collection reflects actual radio conditions, but accuracy deteriorates due to weather and seasonal changes affecting test consistency
Solution Approach 1:
The received radio frequency band is segmented into two distinct components: signal space (containing desired signals) and background space (containing interference and noise). This segmentation allows separate processing and storage of environmental conditions, enabling consistent reproduction of interference patterns while maintaining test reliability across different weather and seasonal conditions.
Solution Approach 2:
The patent creates a copied representation of the real radio environment by recording and storing background space data (interference and noise characteristics) from actual measurements. This copied environmental data can then be reproduced in simulation environments, preserving the accuracy of real conditions while eliminating the variability of conducting repeated real-world tests.
2Reliability
If simulated environment is used, then test consistency is improved, but measurement precision deteriorates because artificial noise differs from real interference
Solution Approach 1:
The patent performs preliminary measurements in the real radio environment to capture and store authentic background space data (interference and noise patterns) before conducting simulations. This pre-recorded real interference data is then used in simulated environments, combining the reproducibility of simulation with the accuracy of real measurements.
Solution Approach 2:
The patent introduces an intermediary component - a database or storage system that holds recorded background space data from real environments. This intermediary bridges the gap between real measurements and simulations, allowing simulated environments to access and reproduce authentic interference patterns without requiring repeated real-world testing.
3Device complexity
If signal and interference are processed together, then processing simplicity is maintained, but signal processing quality deteriorates due to inability to separately analyze background disturbances
Solution Approach 1:
The patent applies segmentation by dividing the received radio frequency band into signal space and background space. This allows the system to process and analyze interference and noise separately from desired signals, improving signal analysis accuracy while maintaining relatively simple processing structures through dedicated signal processing units for each component.

AI summary
A receiver receives at least one radio frequency band. A signal processor separates a signal space associated with the at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one radio frequency band. For a simulation, a memory stores the environment data of the at least one radio system based on the background space under control of the signal processor.
