Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is mapped to multiple signal processing paths, then data processing efficiency is improved, but device complexity increases
Solution Approach 1:
The input stream is segmented into multiple types (first type stream and second type stream), and each type is mapped to different signal processing paths. The baseband packet is divided into header and payload data, with the header containing type information that directs processing. This segmentation allows parallel processing of different data types, improving efficiency while managing complexity through structured division.
Solution Approach 2:
The signal processing apparatus is designed with multi-functional capability to handle both first type streams and second type streams through a unified framework. The same baseband packet structure and header format are used regardless of payload type, allowing the system to process multiple data types through common infrastructure while maintaining specialized processing paths where needed.
2Measurement precision
If detailed header information is included for accurate processing, then measurement precision is improved, but data transmission overhead increases
Solution Approach 1:
Essential identification information is extracted and placed in a dedicated header section, separating type identification data from the payload. The header contains specifically extracted fields (type of payload data, number of first type stream packets) that are sufficient for accurate processing without including unnecessary information, thus maintaining precision while minimizing overhead.
Solution Approach 2:
The header structure uses local quality by providing detailed information only where needed. The type field and packet count field are included specifically in the header portion, allowing receiving apparatus to identify and process payload data appropriately without requiring detailed information throughout the entire data structure. This localized information placement achieves accurate processing with minimal overhead.
