Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a unified receiver processing framework and unified configuration parameters are adopted, then device complexity is reduced and ease of operation is improved, but receiver matching performance with diverse communication environments deteriorates
Solution Approach 1:
The patent implements dynamic receiver configuration by enabling receivers to adaptively adjust their processing parameters based on sensed communication environment characteristics. The system transitions from static unified configuration to dynamic environment-specific configuration, allowing receivers to optimize performance for different channel conditions, interference levels, and signal qualities while maintaining a unified underlying framework.
Solution Approach 2:
The patent changes receiver operating parameters based on environment sensing results. By monitoring communication environment parameters such as channel state, interference characteristics, and signal quality, the system dynamically adjusts receiver configuration parameters including filtering settings, equalization parameters, and detection thresholds to achieve optimal matching between receiver characteristics and environmental conditions.
2Adaptability or versatility
If environment sensing and adaptive receiver matching are implemented, then receiver performance in diverse environments is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent segments the receiver system into distinct functional modules: an environment sensing module that characterizes communication conditions, a parameter determination module that translates sensing results into configuration parameters, and a receiver processing module that executes the adaptive operations. This modular segmentation manages complexity by organizing functions into independent, manageable units with well-defined interfaces.
Solution Approach 2:
The patent performs environment sensing and parameter determination in advance of actual signal reception. By pre-characterizing the communication environment and pre-determining optimal receiver parameters before processing communication signals, the system avoids complex real-time adjustments during signal reception, thereby managing processing complexity while maintaining adaptive performance.
3Measurement precision
If channel estimation and interference analysis are performed to obtain environment information, then sensing precision is improved, but processing time and computational load increase
Solution Approach 1:
The patent implements partial environment sensing by selectively analyzing specific signal characteristics that are most relevant to receiver configuration rather than performing exhaustive analysis of all possible environmental parameters. The system focuses computational resources on extracting the most critical environment information needed for effective receiver matching, thereby achieving sufficient sensing precision with reduced processing time and computational load.
