Mobile Phone Signal Shielding via Frame Reference Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in signal shielding due to the high power consumption by user data modulated signals, which reduces the effectiveness of signal shielding devices.
Innovation Solution
A signaling-type management and control method that synchronizes with the base station's frequency reference, receives frame signals in time division, filters them using multi-frame means to select and enhance the frame reference signal, and uses this signal to shield the base station's transmitting signal, effectively reducing power consumption by user data modulated signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the base station transmits user data modulated signals, then the information transmission capability is improved, but the power consumption increases and shielding efficiency decreases
Solution Approach 1:
The patent extracts only the frame reference signal from the base station's transmitted signal, separating it from the user data modulated signals. By using only the reference signal for shielding purposes, the system eliminates the need to transmit or process the power-consuming user data portion, thereby reducing power consumption while maintaining the shielding function.
Solution Approach 2:
The patent segments the base station signal into distinct components (frame reference signal and user data modulated signal) and selectively processes only the reference signal portion. This segmentation allows the shielding device to operate with a simplified signal structure that consumes less power while still achieving effective shielding.
2Loss of information
If the base station transmits user data modulated signals, then the information transmission capability is improved, but the shielding efficiency deteriorates
Solution Approach 1:
The patent extracts only the frame reference signal from the base station's transmitted signal, separating it from the user data modulated signals. By using only the reference signal for shielding purposes, the system eliminates the need to transmit or process the power-consuming user data portion, thereby reducing power consumption while maintaining the shielding function.
3Reliability
If the frame reference signal is enhanced through multi-frame mean filtering, then the shielding efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-frame mean filtering by collecting and processing multiple frames of reference signals over time. This periodic accumulation and averaging process enhances the signal quality and shielding efficiency by reducing noise and interference, while the systematic approach keeps the complexity manageable through regular temporal sampling.
