BTM Message Adjustment Using Counters to Limit Demodulation Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message adjustment methods in BTM demodulation are prone to errors due to signal jitter, leading to message errors and security vulnerabilities when frequent adjustments are made in fixed intervals.
Innovation Solution
A method and apparatus that utilize a target counter set to limit message adjustments based on predefined limits and counter values, adjusting messages only when necessary to enhance security and reduce errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If message adjustment is performed frequently in fixed length intervals, then message quality can be improved, but message security is affected
Solution Approach 1:
The patent implements dynamic message adjustment by introducing a counter mechanism that tracks the number of adjustments within a time interval. The adjustment frequency is no longer fixed but adapts based on the counter value, allowing the system to perform adjustments when needed while preventing excessive adjustments that would compromise security. The counter increments with each adjustment and resets when reaching a threshold, creating a dynamic control scheme.
Solution Approach 2:
The patent employs feedback control through the counter mechanism that monitors and records the number of message adjustments performed. This feedback information is used to control future adjustment operations, ensuring that adjustments are performed only when necessary and within safe limits. The system uses the counter state to determine whether to proceed with adjustment or skip it, creating a closed-loop control system.
2Speed
If message adjustment is performed without judgment when adjustment request is detected, then response speed is improved, but message security is compromised
Solution Approach 1:
The patent implements preliminary action by pre-establishing a counter mechanism and adjustment limit threshold before message adjustment operations begin. The counter is initialized and the threshold is set in advance, allowing the system to quickly determine whether adjustment is permitted without complex real-time calculations. This preliminary setup enables fast decision-making while maintaining security constraints.
Solution Approach 2:
The patent introduces a counter as an intermediary element between the message adjustment request and the actual adjustment execution. This counter acts as a mediator that controls whether the adjustment operation proceeds or is blocked, providing a buffer between the fast response requirement and the security constraint. The intermediary counter simplifies the decision logic while maintaining security.

AI summary
The invention discloses a message adjustment method, apparatus, device and storage medium, which belongs to the technical field of data processing. The method includes: obtaining a message adjustment limit times and a message adjusted times of a target message adjustment interval; determining a target counter set according to the message adjustment limit times; target counters of the target counter set are arranged in an orderly manner; performing message adjustment on the target message according to the message adjustment limit times, the message adjusted times, and a count value of the target counter in the target counter set when a message adjustment request is detected within the target message adjustment interval. The invention limits the adjustment times of message in BTM demodulation process to a certain extent, improves the quality of messages and reduces message errors, and enhances the security of messages in the BTM demodulation process.
