Echo-Based Noise Cancellation for Signal Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies are inadequate in effectively canceling high-intensity burst noises during signal transportation, particularly when they are long in duration, as they require complex designs for both transmitters and receivers and may not be technology-agnostic.
Innovation Solution
A system that uses a weighted tap delay line and a controller to generate a time-delayed echo of the input signal, which is combined with the original signal to cancel burst noises without requiring additional processing at the transmitter or receiver, and employs recursive noise cancellation techniques to reconstruct the original signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If forward error correction or interleaved signaling is used to compensate for noise bursts, then some noise bursts can be corrected, but the technique is limited to correcting noises with intensity and duration within certain bounds and requires complex transmitter and receiver designs for high intensity long duration bursts
Solution Approach 1:
An intermediary device is introduced between the transmitter and receiver to perform noise cancellation. This intermediary receives the transmitted signal, generates a delayed copy (echo), and subtracts it from the original signal to remove burst noise. The intermediary handles the complex processing while keeping the original transmitter and receiver designs simple and technology-agnostic.
Solution Approach 2:
The intermediary creates a time-delayed copy (echo) of the transmitted signal. This copy is then subtracted from the original received signal to cancel out burst noise. The copying mechanism allows the system to recover the original signal without modifying the transmitter or receiver structures.
2Reliability
If complex signal processing techniques are implemented to handle high intensity long duration burst noises, then noise cancellation performance improves, but the solution is not technology agnostic and requires specific transmitter and receiver designs
Solution Approach 1:
The intermediary device serves as a universal noise cancellation solution that can be deployed with existing communication systems without requiring modifications to the transmitter or receiver. It processes signals from various protocols (DOCSIS 3.0, 3.1, Wi-Fi, etc.) making the system technology-agnostic while maintaining high burst noise cancellation performance.
Solution Approach 2:
The intermediary device is designed to be universally applicable across different communication protocols and systems. It performs the same noise cancellation function regardless of the specific protocol being used, making it a versatile solution that enhances multiple systems without requiring protocol-specific implementations.

AI summary
Signal transport with noise cancellation is contemplated. The noise cancellation may be facilitated with a transmitter configured to induce echoes in a signal desired for transport in order to facilitate subsequently retrieving signal components associated with noise influenced portions of the transported signal from non-noise influence portions of the transported signal.
