Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted through multi-channel in MIMO scheme, then transmission rate is improved, but data receiving synchronization becomes difficult to achieve
Solution Approach 1:
The patent applies preliminary action by calculating receiving power distribution values for each antenna and channel before data reception, and generating a receiving synchronization signal in advance. The synchronization signal is prepared using the power distribution information before actual data transmission begins, ensuring that synchronization is already established when data arrives through multiple channels in MIMO mode.
Solution Approach 2:
The patent introduces a receiving synchronization signal as an intermediary element that mediates between the multi-channel MIMO transmission and the data receiving process. This synchronization signal, generated based on receiving power distribution values, acts as a reference that enables proper alignment and coordination of data reception across multiple antennas and channels, resolving the synchronization difficulty caused by high-rate MIMO transmission.
2Quantity of substance
If large data is transmitted through multi-channel MIMO, then data capacity is improved, but receiving synchronization accuracy deteriorates
Solution Approach 1:
The system performs preliminary calculation of receiving power distribution values for each antenna and channel before receiving large data through MIMO. The receiving synchronization signal is generated in advance based on these power distribution values, ensuring that synchronization accuracy is established before the large data transmission begins, thus maintaining precision despite increased data capacity.
Solution Approach 2:
The patent changes the parameter used for synchronization by utilizing receiving power distribution values across different antennas and channels. Instead of using traditional synchronization methods, the system generates a synchronization signal based on the calculated power distribution parameters, which adapts to the MIMO multi-channel environment and maintains synchronization accuracy even when handling large data volumes.
3Adaptability or versatility
If multi-antenna is used for multi-user service, then service capacity is improved, but synchronization complexity increases
Solution Approach 1:
The patent segments the synchronization process by calculating receiving power distribution values separately for each antenna and each channel in the MIMO system. The receiving synchronization signal is generated based on these segmented calculations, allowing the system to handle multi-user services through multiple antennas while managing synchronization complexity through systematic division of the calculation process.
Solution Approach 2:
The receiving synchronization signal generated by the patent serves multiple functions simultaneously: it provides synchronization for data reception, adapts to different antenna configurations, and supports multi-user services through MIMO. This universal synchronization approach handles various MIMO scenarios (different numbers of antennas, channels, and users) through a single methodology, reducing overall system complexity despite increased adaptability requirements.
