Engineering Contradiction Analysis
1Reliability
If a programmed target is used for data processing, then data processing performance is improved, but the quality of the programmed target becomes unknown and difficult to improve
Solution Approach 1:
The patent implements a feedback mechanism where the signal-to-noise ratio calculated from the equalized output is fed back to adjust the programmed target. The parameter adjustment circuit uses the SNR information to modify the target parameters, creating a closed-loop system that continuously improves target quality based on actual processing performance.
Solution Approach 2:
The patent changes the parameters of the programmed target based on the calculated signal-to-noise ratio. The parameter adjustment circuit modifies target parameters dynamically according to the SNR measurement, allowing the system to adapt to varying signal conditions and optimize performance in real-time.
2Reliability
If the programmed target is adjusted to improve performance, then data processing quality improves, but the complexity of determining optimal parameters increases
Solution Approach 1:
The patent replaces complex manual or iterative parameter optimization methods with an automated signal-to-noise ratio calculation system. By using mathematical computation of SNR from the equalized output, the system automatically determines optimal parameters without requiring complex analysis or manual tuning procedures.
3Ease of operation
If signal to noise ratio is calculated from equalized output, then parameter adjustment becomes possible, but additional calculation complexity is introduced
Solution Approach 1:
The patent performs the signal-to-noise ratio calculation as a preliminary step in the parameter adjustment process. By computing the SNR from the equalized output before parameter adjustment, the system prepares the necessary information in advance, enabling straightforward and efficient parameter optimization without requiring complex real-time computations during the adjustment phase.
