Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission paths are enabled in multi-path transmission mode, then transmission performance and coverage are improved, but device complexity and signal processing requirements increase
Solution Approach 1:
The patent implements dynamic switching between single-path and multi-path transmission modes based on communication-related indicators. The transmitter can adaptively enable or disable additional transmission paths according to channel conditions, thereby improving transmission performance when needed while reducing device complexity when multi-path mode is not required.
Solution Approach 2:
The patent dynamically adjusts complex gain settings (including gain values and phase values) for each transmission path based on communication-related indicators. By changing these parameters adaptively, the system optimizes transmission performance in multi-path mode while maintaining the ability to simplify operation in single-path mode, thus managing the trade-off between performance and complexity.
2Reliability
If dynamic adjustment of complex gain settings is implemented, then signal transmission quality is improved, but control complexity increases
Solution Approach 1:
The patent employs feedback mechanisms by monitoring communication-related indicators and using this information to adaptively adjust complex gain settings. The system continuously monitors transmission quality metrics and modifies gain values and phase values accordingly, improving transmission quality while automating the control process to manage complexity.
Solution Approach 2:
The transmitter performs self-adjustment of complex gain settings based on monitored communication indicators without requiring external intervention. The system automatically generates and applies configuration information for gain and phase adjustments, thereby improving transmission quality while reducing the burden on external control systems.
3Adaptability or versatility
If adaptive generation of configuration information is performed based on communication indicators, then transmission adaptability is improved, but processing time and computational load increase
Solution Approach 1:
The patent pre-generates configuration information for complex gain settings based on monitored communication indicators. By preparing adjustment parameters in advance based on current channel conditions, the system enables rapid adaptation when transmission conditions change, improving adaptability while reducing the processing time required during actual transmission mode switches.

AI summary
A transmitter (1) is provided and includes a plurality of transmission paths (12, 13), a configure module (10) and a control module (11). Each of the transmission paths (12, 13) comprises a corresponding antenna (125, 135). The configure module (10) is configured to obtain a communication-related indicator during the transmitter operating in a multi-path transmission mode, in which multiple transmission paths among the plurality of transmission paths (12, 13) are enabled, and adaptively generate configuration information (D10) to a control module (11) in response to changes of the communication-related indicator for dynamically adjusting the complex gain setting of the multiple transmission paths (12, 13), wherein the complex gain setting comprises at least one gain value and at least one phase value. The control module (11) is configured to generate corresponding transmission data (DOUT30, DOUT31) for the multiple transmission paths (12, 13) according to received input data (DIN) and the configuration information (D10).
