Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-channel wired communication links experience significant crosstalk issues due to line lengths, discontinuities, and impedance mismatches, leading to reduced channel capacity and quality, especially at higher frequencies.
Innovation Solution
Adjusting the transmission power and reception sensitivity of signal carriers on coupled communication lines such that the receiver signal strength on adjacent lines is kept below a predetermined comparison value, allowing for reduced crosstalk and improved channel separation without individual tuning of signal carriers or reception sensitivities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-channel wired communication link is used to improve channel capacity, then data transmission capability is improved, but crosstalk between lines increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the transmission power of signal carriers based on detected crosstalk levels. When crosstalk is detected on a communication line, the system modifies the power parameters of signal carriers on coupled lines to reduce interference, thereby maintaining high channel capacity while mitigating the harmful crosstalk effect.
2Reliability
If signal carrier power is increased to improve transmission quality, then communication reliability is improved, but crosstalk to adjacent lines increases
Solution Approach 1:
The patent implements feedback by continuously monitoring communication lines for crosstalk and using this information to adjust transmission power levels. The system detects crosstalk conditions and feeds this information back to the transmission device, which then modifies signal carrier power to maintain reliable communication while preventing excessive interference to adjacent lines.
Solution Approach 2:
The patent applies dynamics by making the transmission power of signal carriers adjustable and adaptive rather than fixed. The system dynamically changes power levels based on real-time detection of crosstalk conditions, allowing optimal balance between communication reliability and crosstalk suppression under varying operational conditions.
3Manufacturing precision
If individual tuning of signal carriers is performed to reduce crosstalk, then channel separation is improved, but device complexity increases
Solution Approach 1:
The patent applies merging by combining multiple signal carriers into a composite signal that is transmitted together. Instead of individually tuning each carrier, the system processes and transmits multiple carriers as a unified signal, simplifying the tuning process while maintaining channel separation through the combined signal structure.
