Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the length of redundant data is increased to improve error detection accuracy, then error detection accuracy is improved, but frequency utilization efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the length of error detection data variable rather than fixed. The generation unit dynamically adjusts the length of error detection data based on the length of encoded sequences or estimated error rates, allowing the system to optimize between error detection accuracy and frequency utilization efficiency under different operating conditions.
Solution Approach 2:
The patent changes the parameter of error detection data length from a fixed value to a variable parameter. By generating error detection data with different lengths according to predetermined conditions (encoded sequence length or estimated error rate), the system can adaptively optimize the balance between detection accuracy and spectral efficiency.
2Productivity
If the length of redundant data is decreased to improve frequency utilization efficiency, then frequency utilization efficiency is improved, but error detection accuracy deteriorates
Solution Approach 1:
The system dynamically adjusts the error detection data length based on actual communication conditions. When error rates are low or encoded sequences are short, the system uses shorter error detection data to maximize frequency utilization efficiency while maintaining adequate detection capability.
Solution Approach 2:
The patent varies the parameter of error detection data length according to predetermined conditions such as encoded sequence length or estimated error rates, enabling the system to reduce redundant data when possible while maintaining necessary error detection accuracy.
3Device complexity
If fixed length error detection data is used, then system complexity is reduced, but frequency utilization efficiency deteriorates due to inability to adapt to different conditions
Solution Approach 1:
The patent introduces dynamic adaptation by making error detection data length variable based on communication conditions. The generation unit responds to changes in encoded sequence length or estimated error rates, allowing the system to optimize frequency utilization without requiring complex manual configuration.
