Engineering Contradiction Analysis
1Productivity
If multiple antennas operate simultaneously in different antenna roles, then communication capacity and throughput are improved, but antenna interference and orthogonality issues occur
Solution Approach 1:
The patent segments the antenna system into multiple antenna sequence groups, where each group contains antennas operating in specific roles. By dividing the antenna system into manageable sequences and evaluating each sequence's performance independently, the patent can identify and adjust specific antenna combinations that cause interference while maintaining overall system throughput.
Solution Approach 2:
The patent dynamically adjusts antenna operating parameters by detecting performance metrics of different antenna sequence groups and switching between sequences based on detected interference levels and communication quality. This parameter change approach allows the system to adapt to varying interference conditions while maintaining optimal throughput.
2Reliability
If antenna performance is optimized for maximum throughput, then communication quality improves, but antenna interference and orthogonality problems worsen
Solution Approach 1:
The patent implements a feedback mechanism that continuously detects performance parameters of antenna sequence groups and uses this information to determine which antenna sequence to activate. The system monitors communication quality and interference levels, then adjusts antenna sequence selection accordingly, creating a closed-loop control system that balances throughput optimization with interference mitigation.
Solution Approach 2:
The patent employs dynamic antenna sequence switching, where the antenna configuration is not fixed but changes based on real-time detection of interference conditions and communication quality. This dynamic approach allows the system to transition between different antenna sequences to maintain optimal performance while avoiding interference-prone configurations.
