Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If space-time block-coding (STBC) is used to transmit data streams via multiple transmitting paths, then transmission performance is improved, but power consumption is increased
Solution Approach 1:
The patent implements dynamic selection of transmitting paths and space block-coding execution based on real-time transmission quality detection. The system transitions from static to dynamic operation by adjusting the number of active transmitting paths and whether to execute space block-coding according to channel conditions, thereby optimizing the balance between transmission performance and power consumption
Solution Approach 2:
The system changes operational parameters (number of transmitting paths, space block-coding execution status) based on detected transmission quality. By varying these parameters dynamically, the system adapts to changing channel conditions and optimizes power consumption while maintaining required transmission performance
2Productivity
If the number of transmitting paths is increased for high-speed data transmission, then data transmission rate is improved, but device complexity is increased
Solution Approach 1:
The patent employs dynamic path selection where the number of active transmitting paths is adjusted based on transmission quality detection. This allows the system to use more paths when high data transmission rate is needed and channel conditions permit, while reducing the number of active paths when complexity reduction is prioritized, achieving adaptive optimization
Data Source
AI summary
A transmitting method and transmission system using the same is applied to selectively use a space block-coding module to transmit a transmitted data. Each data stream of the transmission data is transmitted using the transmitting paths, and the transmission qualities of the transmitting paths are detected to decide whether the space-block encoding module works or not.
