Receiver Power Scaling Through Channel-Aware Performance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems fail to adapt power consumption based on varying signal conditions, leading to inefficient power usage and suboptimal performance, as they do not account for changes in communication channel quality, signal characteristics, and error rates.
Innovation Solution
A system that quantitatively estimates receive signal factors and maps these to receiver performance parameters, adjusting power consumption by controlling RF dynamic range, baseband dynamic range, channel equalization, and phase noise, while incorporating feedback mechanisms to ensure minimum required performance is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If conventional communication systems maintain fixed performance settings, then system reliability is maintained, but power consumption increases unnecessarily when signal conditions are good
Solution Approach 1:
The patent implements dynamic adjustment of receiver performance parameters based on real-time signal condition assessment. The system continuously monitors signal quality metrics and adapts performance settings accordingly, transitioning from static fixed-performance operation to dynamic adaptive operation that matches actual channel conditions.
Solution Approach 2:
The system changes operational parameters such as processing gain, spreading code length, and receiver complexity based on assessed signal conditions. When signals are easier to receive, the system reduces these parameters to lower power consumption; when conditions deteriorate, parameters are increased to maintain reliability.
2Reliability
If receiver performance parameters are increased to maintain minimum required performance under all conditions, then reliability is improved, but power consumption increases even when not needed
Solution Approach 1:
The patent employs feedback mechanisms that continuously assess signal conditions and use this information to adjust receiver performance parameters. The system monitors received signal quality and feeds this information back to the performance control logic, creating a closed-loop system that maintains reliability only when necessary while reducing power consumption during favorable conditions.
Solution Approach 2:
The system dynamically adjusts performance parameters based on real-time signal assessments rather than maintaining fixed high-performance settings. This dynamic approach ensures minimum required performance is met when signal conditions demand it, while allowing power consumption to be reduced when conditions are favorable.
3Use of energy by stationary object
If the system reduces performance parameters to save power, then power consumption decreases, but the ability to handle varying signal conditions and blockers deteriorates
Solution Approach 1:
The system dynamically adjusts performance parameters based on real-time signal condition assessments rather than maintaining fixed settings. This allows the receiver to optimize the balance between power consumption and handling capability, adapting to varying signal conditions and blocker presence as they occur.
Solution Approach 2:
The patent changes operational parameters such as processing gain and receiver complexity based on assessed signal conditions including blocker presence. When blockers are detected or signal conditions deteriorate, the system increases relevant parameters to maintain handling capability while keeping power consumption low during favorable conditions.
