Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless relay amplification systems experience power attenuation during signal relay due to varying signal power, leading to inconsistent link gains between antennas.
Innovation Solution
The system adjusts the gains of the first and second RF transceivers based on the power variation of the I/Q signals to maintain consistent power and link gain between antennas, ensuring a fixed-gain state during uplink or downlink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the relay amplification system amplifies signals with varying power, then the signal coverage is expanded, but the link gain becomes inconsistent between antennas
Solution Approach 1:
The patent implements dynamic gain adjustment by continuously monitoring the power of received I/Q signals and adjusting the gain of RF transceivers in real-time. The baseband chip calculates power variations and dynamically controls the gain parameters of both the first and second RF transceivers to maintain consistent link gain despite varying signal conditions
Solution Approach 2:
The system employs a feedback mechanism where the baseband chip continuously monitors the power of I/Q signals from both antennas, compares the power levels, and adjusts the gain parameters accordingly. This closed-loop control ensures that link gain remains consistent by using the power measurement feedback to drive gain adjustments
2Stability of the object's composition
If the system maintains fixed gain between antennas, then link gain consistency is achieved, but power attenuation occurs during signal relay
Solution Approach 1:
The system transitions from fixed gain to dynamic gain adjustment, where the gain parameters of RF transceivers are continuously adapted based on real-time power measurements of I/Q signals. This dynamic adjustment prevents power attenuation by ensuring that gain changes compensate for signal power variations during relay amplification
Solution Approach 2:
The patent changes the gain parameter of RF transceivers dynamically based on power variations detected in I/Q signals. The baseband chip calculates power differences and adjusts gain parameters accordingly, transforming the system from static to adaptive parameter control to prevent energy loss during signal relay
3Loss of energy
If the system adjusts gain dynamically based on power variation, then power attenuation is prevented, but device complexity increases
Solution Approach 1:
The baseband chip performs multiple functions: it processes I/Q signals, calculates power variations, determines gain adjustments, and controls both RF transceivers. This multi-functionality consolidates the complexity into a single component rather than requiring separate dedicated circuits for each function
Solution Approach 2:
The system uses its own received signals to automatically adjust its gain parameters. The baseband chip monitors the power of I/Q signals and self-regulates the gain of RF transceivers without external intervention, making the system self-adaptive and reducing the need for external control mechanisms
