Adaptive Communication Noise Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems are inadequate in accurately accounting for changes in impulse noise during data transfer, leading to inefficiencies and errors in noise-related data transfer.
Innovation Solution
The method involves determining an initial impulse noise protection value and adjusting the number of redundancy bits added to data blocks to form codewords, allowing for adaptive impulse noise protection without interrupting communication services, by dynamically adjusting Forward Error Correction (FEC) and interleaver parameters based on monitored noise levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of redundancy bits is increased to improve impulse noise protection, then the reliability of data transfer is improved, but the data rate decreases
Solution Approach 1:
The system dynamically adjusts the impulse noise protection level by modifying FEC and interleaver parameters based on real-time noise monitoring, allowing the redundancy bits to vary adaptively rather than remaining fixed, thus optimizing the balance between reliability and data rate
Solution Approach 2:
The invention changes system parameters (FEC parameters and interleaver depth) to adjust the number of redundancy bits added to data blocks, enabling flexible control over the trade-off between noise protection and data transmission efficiency
2Device complexity
If existing fixed impulse noise protection methods are used, then the system complexity is kept low, but the system cannot accurately account for changes in impulse noise during data transfer
Solution Approach 1:
The system implements feedback by monitoring impulse noise levels during data transfer and using this information to dynamically adjust FEC and interleaver parameters, enabling the system to adapt to changing noise conditions while maintaining manageable complexity through automated control
Solution Approach 2:
The system performs self-adjustment by automatically monitoring its own noise environment and modifying its protection parameters without external intervention, allowing adaptive noise protection to emerge from the system's own operational data

AI summary
One embodiment of the present invention relates to a method of transferring data in a communication system. In the method, an initial impulse noise protection value is determined. A number of redundancy bits is added to blocks of data to form codewords as a function of the initial impulse noise protection value, where the impulse noise protection value corresponds to a number of consecutive symbols that can be corrected. The number of symbols that can be correctly transmitted is changed by changing only the number of redundancy bits added to each block of data.
