Signal Analysis Apparatus for Error Source Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal analysis methods for pulse modulated signals do not effectively identify the source of errors in faulty data transmission, only correcting errors without revealing the underlying cause.
Innovation Solution
A signal analysis apparatus comprising a decoder module, error correction module, and processing module that decodes input signals, identifies errors, generates a data set with error information, and performs forward error correction using redundant data to pinpoint error sources within the transmission path, and visualizes this information for debugging.

Engineering Contradiction Analysis
1Reliability
If error correction methods are used to reduce symbol error rate, then reliability of data transmission is improved, but the underlying problem (error source) remains hidden
Solution Approach 1:
The patent segments the transmission path into multiple sections (e.g., preamble, data, CRC portions) and tracks errors at each segment level. The error correction module identifies which specific segment contains the error, allowing the system to maintain reliability while providing localized information about the error source without exposing the entire transmission path.
Solution Approach 2:
The patent introduces an intermediary error identification mechanism that acts between the signal reception and error correction processes. This intermediary layer (error correction module with error identification capability) provides information about error locations without interfering with the overall error correction function, thus maintaining reliability while revealing error source information.
2Reliability
If traditional error correction is applied, then symbol error rate is reduced, but debugging capability of transmission path is lost
Solution Approach 1:
The transmission path is divided into measurable segments (preamble, data, CRC portions), and the error correction module is configured to identify which segment contains errors. This segmentation enables the system to maintain low symbol error rates through correction while providing clear identification of error locations for debugging purposes.
Solution Approach 2:
The patent implements a feedback mechanism where the error correction module provides information about error locations back to the processing module. This feedback loop enables continuous monitoring and debugging of the transmission path while maintaining reliable error correction, as the system learns from error patterns without compromising correction effectiveness.

AI summary
A signal analysis apparatus for analyzing an input signal is described. The input signal includes a symbol sequence. The symbol sequence includes data information and redundant data information. The signal analysis apparatus includes one or more circuits composed of a decoder module, an error correction module, and a processing module.
