Correlation-Based Data Alignment Circuit for Synchronization Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing systems face inefficiencies when synchronization information is not detectable due to noise or other factors, leading to costly processing time as data may need to be repeatedly re-framed and re-decoded to recover the original data.
Innovation Solution
The implementation of a data processing system that includes a sample buffer circuit, data detector circuit, data decoder circuit, and mis-alignment determination circuit, which uses correlation-based methods to realign data fragments by identifying mis-alignment values and applying decoding algorithms to recover data even without detectable synchronization marks.

Engineering Contradiction Analysis
1Reliability
If data is repeatedly re-framed and re-decoded to recover original data when synchronization is not detected, then data recovery is achieved, but processing time increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing correlation values between synchronization patterns and data patterns before actual data recovery is needed. When synchronization is lost, the system can immediately use these pre-computed correlation values to determine misalignment without performing repeated full decoding operations, thus achieving fast data recovery while minimizing processing time
Solution Approach 2:
The patent replaces the mechanical iterative re-framing and re-decoding process with a computational correlation-based approach. Instead of physically re-aligning data through multiple decoding passes, the system uses correlation calculations to mathematically determine the misalignment offset and correct it in a single operation, substituting a complex mechanical process with a more efficient computational method
2Loss of time
If correlation-based methods are used to realign data fragments, then processing time is reduced, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary correlation calculation mechanism that bridges the gap between simple data storage and complex iterative decoding. The correlation values act as an intermediate layer that captures the relationship between synchronization patterns and data patterns, allowing the system to determine misalignment efficiently without requiring full decoding complexity, thus reducing processing time while controlling system complexity through modular design
