Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems face inefficiencies in data transmission due to the need for synchronization words, which can be overly long, affecting efficiency, or overly short, leading to missed synchronization, and require storage of specific patterns for recognition, increasing complexity and storage needs.
Innovation Solution
A method and device for frame synchronization that generates a frame parameter field with a set pattern, packs it with payload data, and sends it without a synchronization word, allowing the receiving end to identify the frame parameter field using autocorrelation processing, reducing the need for pattern storage and multiple recognition operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a synchronization field is made longer to ensure reliable detection, then the reliability of frame synchronization is improved, but the data transmission efficiency deteriorates due to increased overhead
Solution Approach 1:
The patent extracts the synchronization function from a dedicated synchronization field and integrates it into the frame parameter field. The frame parameter field is designed with a specific pattern that enables autocorrelation detection, allowing the receiver to identify frame boundaries without requiring a separate synchronization field. This eliminates the trade-off between synchronization reliability and transmission efficiency by embedding synchronization capability within the existing data structure.
2Productivity
If a synchronization field is made shorter to improve transmission efficiency, then the data transmission efficiency is improved, but the reliability of frame synchronization deteriorates as the synchronization field may be missed
Solution Approach 1:
The frame parameter field serves dual purposes: it carries frame parameter information and simultaneously provides synchronization functionality. By designing the frame parameter field with a specific pattern that exhibits autocorrelation properties, the field becomes self-sufficient for both information transmission and frame boundary detection, eliminating the need for a separate synchronization field and its associated reliability-efficiency trade-off.
3Reliability
If conventional synchronization words are used, then frame synchronization can be achieved, but the device complexity increases due to the need to store and compare specific synchronization patterns
Solution Approach 1:
The frame parameter field with its specific pattern design enables the receiver to perform autocorrelation processing directly on the received signal. This self-service approach eliminates the need for the receiver to store pre-defined synchronization patterns and perform complex pattern matching operations. The autocorrelation method automatically identifies frame boundaries based on the inherent periodicity of the frame parameter field pattern, significantly reducing device complexity.
4Reliability
If a dedicated synchronization field is used, then frame synchronization can be reliably achieved, but the loss of information increases due to the overhead of the synchronization field
Solution Approach 1:
The patent merges the synchronization function with the frame parameter field, combining what were previously separate functions into a single integrated structure. The frame parameter field is designed with a specific pattern that enables it to serve both as carrier of frame parameter information and as a synchronization signal. This merging eliminates the redundant overhead of a dedicated synchronization field, reducing information loss while maintaining synchronization reliability.

AI summary
The present application relates to a data processing method and device for frame synchronization, a communication system, a communication device, a communication apparatus and a storage medium. The method includes: processing frame parameter information to generate a frame parameter field with a set pattern; packing the frame parameter field with payload data to obtain frame structure data; and sending the frame structure data, wherein the set pattern is used by a receiving end to position the frame parameter field in a received data stream, and subsequently to obtain the frame structure data from the data stream based on the frame parameter field. The above method enables the receiving end to determine the start position of the data frame sent from the sending end without using the synchronization word in the communication system, which improves the efficiency of data transmission in the communication system.
