Engineering Contradiction Analysis
1Productivity
If electromagnetic signals are transmitted directly without transformation, then signal integrity is maintained, but transmission resource consumption increases and efficiency decreases
Solution Approach 1:
The patent extracts redundant information from electromagnetic signals by transforming them into complex signals and removing unnecessary components. The transformation process separates essential signal characteristics from redundant data, allowing efficient transmission of only the critical information while maintaining signal integrity.
Solution Approach 2:
The patent changes the parameter representation of signals by transforming real signals into complex signals with multiple dimensions (space, time, delay-frequency). This parameter transformation enables more efficient encoding and compression, reducing the resources needed for transmission while preserving all necessary signal characteristics.
2Loss of energy
If signal compression is applied to reduce transmission resources, then radio transmission resource consumption decreases, but signal reconstruction precision deteriorates
Solution Approach 1:
The patent introduces additional dimensions (space dimension, time dimension, delay-frequency dimension) to represent signal characteristics. By expanding the signal representation into multiple dimensions, the system can compress data more effectively while preserving all essential information, thereby maintaining reconstruction precision even with reduced transmission resources.
Solution Approach 2:
The patent creates a composite signal structure combining multiple signal components (complex signals with phase and amplitude information) that work together to preserve signal integrity during compression. This composite approach allows aggressive compression while maintaining the ability to reconstruct the original signal with high precision.
3Adaptability or versatility
If traditional compression algorithms are used, then general applicability is achieved, but electromagnetic signal characteristics and channel transmission impacts are neglected
Solution Approach 1:
The patent applies local quality by tailoring the compression algorithm specifically for electromagnetic signals with particular characteristics (phase, amplitude, multi-dimensional structure). Instead of using a generic compression approach, the system optimizes the transformation and compression process to preserve the specific properties of electromagnetic signals, thereby improving processing accuracy for this signal type.
