Engineering Contradiction Analysis
1Use of energy by moving object
If discontinuous packet transmission is implemented, then power consumption is reduced and range is extended, but transmission performance and reliability deteriorate compared to continuous transmission
Solution Approach 1:
The packet transmission is segmented into multiple portions, each transmitted at a different PRF. The first portion is transmitted at a first selected PRF and the second portion is transmitted at a second selected PRF, allowing the system to optimize power consumption while maintaining transmission reliability through diversified transmission parameters
Solution Approach 2:
The system dynamically adjusts the PRF for different packet portions based on transmission requirements. By selecting different PRFs for different portions and enabling discontinuous transmission when appropriate, the system adapts to varying power and performance requirements in real-time
2Adaptability or versatility
If variable PRF is used for different packet portions, then adaptability and power efficiency are improved, but system complexity increases
Solution Approach 1:
Different portions of the packet are transmitted with different local qualities (PRFs) suited to their specific requirements. The first portion uses a first selected PRF and the second portion uses a second selected PRF, allowing each portion to be optimized independently while maintaining overall system manageability
