Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices with high error correction capabilities face a trade-off between improved transmission characteristics and increased power consumption due to the large circuit scale required for effective error correction.
Innovation Solution
The implementation of a communication device that utilizes a combination of error correction circuits with different error correction capabilities and power consumption levels, where a high-capability error correction circuit is used for transmission lines with low error rates and a lower-capability circuit for those with higher error rates, optimizing the distribution of data across multiple transmission lines to improve overall transmission characteristics while minimizing power consumption.

1Reliability
If an error correction circuit with high error correction capability is used, then transmission characteristics are improved, but power consumption increases
Solution Approach 1:
The error correction function is segmented across multiple transmission lines, each with different error correction capabilities. High-capability error correction circuits are applied to transmission lines with better characteristics, while lower-capability circuits are used for lines with poorer characteristics. This segmentation allows the system to achieve overall high reliability without requiring all transmission lines to use high-power error correction circuits.
Solution Approach 2:
Different error correction capabilities are assigned to different transmission lines based on their individual characteristics. Transmission lines with better quality (lower error rates) receive high-capability error correction circuits, while lines with poorer quality receive lower-capability circuits. This local optimization ensures that each transmission line gets the appropriate level of error correction without overspending power on all lines uniformly.
2Reliability
If an error correction circuit with high error correction capability is used, then data errors are reduced, but circuit scale increases
Solution Approach 1:
The error correction function is divided and distributed across multiple transmission lines rather than using a single high-capability circuit for all lines. Each transmission line is equipped with an error correction circuit matched to its specific characteristics, avoiding the need for a universally high-capability circuit that would increase overall system complexity.
Solution Approach 2:
Each transmission line is equipped with an error correction circuit whose capability is matched to the line's specific characteristics. This localized approach ensures that circuit complexity is optimized for each individual line's needs, rather than uniformly high complexity across all lines, thereby reducing overall device complexity while maintaining data error reduction.
