Radio Receiver Diversity Reception Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio receivers face challenges in managing power consumption while implementing diversity reception, which is crucial for portable devices relying on battery power, as the activation of diversity reception schemes increases power consumption without providing significant benefits for all types of applications.
Innovation Solution
A control unit is implemented to dynamically activate or disable diversity reception based on the application type, communication channel type, data rate stability, and quality-of-service requirements, allowing for efficient power management by prioritizing power savings in real-time applications and enabling diversity reception for non-real-time applications that benefit from improved data rates and reduced error rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diversity reception is activated to improve signal detection reliability, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of diversity reception by activating it only when specific conditions are met (signal quality threshold not satisfied or data error rate threshold not satisfied). The control unit continuously monitors signal conditions and dynamically switches between diversity reception and normal reception modes, making the system adaptive rather than static.
Solution Approach 2:
The patent changes the operational parameters of the reception system by switching between different reception modes (diversity reception with multiple signal paths vs. normal reception with single signal path) based on measured signal parameters such as signal quality and data error rate, thereby optimizing the balance between reliability and power consumption.
2Reliability
If diversity reception is activated to reduce data error rate, then data error rate is reduced, but power consumption increases
Solution Approach 1:
The patent employs feedback mechanisms by continuously monitoring the data error rate of received data and using this information to control whether diversity reception should be activated. The control unit receives feedback about signal conditions and error rates, and adjusts the reception mode accordingly to maintain reliability while minimizing power consumption.
Solution Approach 2:
The system dynamically adjusts the reception mode based on real-time monitoring of data error rates. When the error rate exceeds a threshold, diversity reception is activated; when it falls below the threshold, normal reception is sufficient. This dynamic adjustment ensures optimal performance without unnecessary power consumption.
3Reliability
If diversity reception is continuously activated to maintain signal quality, then signal quality is maintained, but battery life is reduced
Solution Approach 1:
The patent implements periodic monitoring of signal conditions and error rates, activating diversity reception only during periods when signal quality deteriorates or error rates increase. Instead of continuous activation, the system periodically assesses whether diversity reception is needed and activates it only during necessary time intervals, thereby conserving battery life while maintaining signal quality when required.
