Solution Overview
Problem
Existing technologies have not adequately addressed the issue of reducing power consumption during signal reception in mobile devices, which limits their operating time, especially in applications where continuous energy supply is not available.
Innovation Solution
A circuit and method that switch the receiver into a non-ready-to-receive state during parts of a signal block, utilizing redundant encoding to conserve power, with the control circuit managing the transition based on signal quality and operational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver circuit continuously monitors and receives the entire signal block, then the signal reception reliability is improved, but the power consumption increases
Solution Approach 1:
The signal block is divided into multiple sub-blocks, and the receiver circuit is segmented to process only necessary sub-blocks. The control circuit determines which sub-blocks need to be received based on redundancy information, allowing the receiver to skip monitoring certain sub-blocks while maintaining reliable signal reception through selective processing.
Solution Approach 2:
The receiver circuit performs partial action by not continuously monitoring all sub-blocks of the signal. Instead, it selectively receives only the minimum necessary sub-blocks required to reconstruct the payload, leveraging redundant encoding to achieve reliable reception with reduced power consumption.
2Use of energy by moving object
If the receiver circuit is switched to non-ready-to-receive state during parts of the signal block, then the power consumption is reduced, but the signal reception completeness may be compromised
Solution Approach 1:
Redundant encoding is applied preliminarily to the signal block before transmission, creating multiple sub-blocks that contain redundant payload information. This preliminary action enables the receiver to successfully reconstruct the payload even when switching to non-ready-to-receive state during certain sub-blocks, as the received sub-blocks contain sufficient information for complete payload recovery.
3Use of energy by moving object
If redundant encoding is used to allow selective sub-block reception, then the power consumption during reception is reduced, but the device complexity increases
Solution Approach 1:
A control circuit is implemented that monitors signal quality and determines which sub-blocks need to be received based on redundancy information. This feedback mechanism allows the receiver to dynamically adjust its reception strategy, switching between ready-to-receive and non-ready-to-receive states based on actual signal conditions, thereby managing complexity while maintaining power efficiency.
