Engineering Contradiction Analysis
1Reliability
If the code block length is dynamically adjusted according to information bit size and code rate, then the spectral efficiency and reliability are improved, but the hardware implementation complexity and delay increase
Solution Approach 1:
The patent applies dynamics by enabling the code block length to be dynamically adjusted according to information bit size and code rate requirements. The encoder can adaptively change the code block length within a predetermined range, allowing the system to optimize spectral efficiency and reliability for different transmission scenarios while managing hardware complexity through controlled adaptability.
2Reliability
If the code block length is dynamically adjusted, then the information transmission reliability is improved, but the encoding delay increases
Solution Approach 1:
The patent implements dynamic code block length adjustment that adapts to different transmission requirements. By allowing the code block length to vary within a predetermined range based on information bit size and code rate, the system can optimize reliability while managing encoding delay through adaptive rather than purely static or fully dynamic approaches.
3Productivity
If the code block length is increased to improve spectral efficiency, then the spectral efficiency is improved, but the hardware implementation becomes impossible due to limited capability
Solution Approach 1:
The patent applies parameter changes by introducing a predetermined range for code block length and dynamically adjusting the code block length within this range based on information bit size and code rate. This allows the system to optimize spectral efficiency by selecting appropriate code block lengths without exceeding hardware implementation capabilities, as the range is predetermined to be feasible for the hardware.
