Relay Amplifier Switching Based on Receiver Distortion Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to adaptively utilize relays by effectively responding to situations where distortion compensation is available or not in receivers, leading to suboptimal power efficiency and modulation accuracy.
Innovation Solution
A receiver with a nonlinear distortion compensation function notifies the relay or transmitter to enable the amplifier to operate in a nonlinear region, allowing adaptive response to optimize power efficiency and modulation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the relay amplifier operates in the nonlinear region to improve power efficiency, then power efficiency is improved, but modulation accuracy deteriorates when the receiver does not have distortion compensation
Solution Approach 1:
The relay dynamically changes its operating region based on the receiver's distortion compensation capability. When the receiver supports distortion compensation, the relay operates in the nonlinear region for high power efficiency. When the receiver does not support distortion compensation, the relay operates in the linear region to ensure modulation accuracy. This dynamic adaptation resolves the contradiction between power efficiency and modulation accuracy.
Solution Approach 2:
The operating parameter of the relay amplifier (operating region) is changed based on the receiver's capabilities. By switching between linear and nonlinear operating regions, the system optimizes power efficiency when distortion compensation is available while maintaining modulation accuracy when it is not available.
2Measurement precision
If the relay operates in the linear region to ensure modulation accuracy, then modulation accuracy is maintained, but power efficiency decreases
Solution Approach 1:
The relay dynamically adjusts its operating region based on real-time information about the receiver's distortion compensation capability. This dynamic operation allows the system to achieve high power efficiency when the receiver can compensate for distortion, while still maintaining modulation accuracy when the receiver cannot compensate.
Solution Approach 2:
The system uses feedback information about the receiver's distortion compensation capability to control the relay's operating region. This feedback mechanism enables the relay to adapt its operation to achieve optimal power efficiency while ensuring modulation accuracy is maintained when distortion compensation is not available.
3Use of energy by moving object
If the relay operates near saturation region to increase operating region and power efficiency, then power efficiency increases, but distortion occurs
Solution Approach 1:
The system converts the harmful distortion generated by nonlinear operation into a beneficial situation by using the receiver's distortion compensation capability. When the receiver supports distortion compensation, it can compensate for the distortion generated by the relay's nonlinear operation, allowing the relay to operate at high power efficiency without degrading the overall system performance.
Solution Approach 2:
The operating parameters of the relay are changed based on the receiver's distortion compensation capability. By switching between linear and nonlinear operating regions, the system allows the relay to operate near saturation for high power efficiency when distortion can be compensated, while avoiding distortion when compensation is not available.
