Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the equalizer is operated in a high power mode to increase compensation for signal attenuation, then signal quality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power mode switching in the equalizer by detecting eye-width parameters and automatically adjusting between high and low power modes. The equalizer transitions from a static operation mode to a dynamic adaptive mode where the power consumption level is adjusted in real-time based on signal quality measurements, resolving the contradiction between maintaining high signal quality and reducing power consumption.
Solution Approach 2:
The patent changes the operating parameters of the equalizer by using eye-width detection as a feedback mechanism. When the detected eye-width indicates poor signal quality, the equalizer switches to high power mode with increased compensation parameters. When signal quality is good, it switches to low power mode with reduced compensation parameters, thereby adapting the system parameters to match actual signal conditions and eliminate the fixed trade-off between power consumption and signal quality.
2Device complexity
If the equalizer uses a single fixed parameter configuration, then device complexity is reduced, but adaptability to different signal transmission environments deteriorates
Solution Approach 1:
The patent enables the equalizer to self-adjust its operating parameters through automatic eye-width detection and power mode selection. The system performs self-diagnosis of signal quality conditions and self-corrects by switching between different power modes and parameter configurations without external intervention, thereby achieving high environmental adaptability while maintaining relatively simple device architecture.
Solution Approach 2:
The patent implements a feedback mechanism where the equalizer continuously monitors eye-width parameters of the received signal and uses this feedback information to automatically adjust its operating mode. The detected eye-width serves as feedback that triggers parameter changes in the equalizer, creating a closed-loop control system that adapts to different transmission environments while keeping the control logic relatively simple.

AI summary
A signal modulation method, an adaptive equalizer and a memory storage device are provided. The method includes: receiving a first signal; performing a first modulation on the first signal based on a first power mode to generate a second signal having a first eye-width; performing a second modulation based on a second power mode to generate the second signal having a second eye-width; determining whether the first eye-width and the second eye-width meet a first condition; if yes, performing a third modulation based on the first power mode to generate the second signal having a third eye-width; otherwise, performing the third modulation based on the second power mode to generate the second signal having the third eye-width. Therein, a power consumption of performing the second modulation is less than that of performing the first modulation. Therefore, an efficiency of the adaptive equalizer may be improved.
