Dummy Synchronization Patterns for Communication Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jamming systems are inefficient due to high power consumption, lack of scalability, adaptability, and flexibility, and often require dedicated equipment, making them costly and discreet, while also being easily detectable or complex, which limits their effectiveness and range.
Innovation Solution
A method that introduces dummy synchronization patterns into the communication system's payload data to scramble the signal, allowing for low-cost jamming without modifying the transmitter equipment, and utilizing multiple terminals to create a network of cooperative jammers that increase neutralization performance and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated jamming equipment is used, then jamming effectiveness is improved, but cost and device complexity increase
Solution Approach 1:
The patent applies universality by enabling standard communication terminals to perform dual functions: normal communication and jamming. The terminal equipment uses its existing transmission capabilities to send dummy synchronization patterns, transforming ordinary devices into multi-functional units that can jam without requiring dedicated jamming hardware.
Solution Approach 2:
The patent implements self-service by having the terminal generate and transmit jamming signals using its own resources. The terminal utilizes its built-in synchronization pattern generation and transmission chain to create dummy patterns, eliminating the need for external jamming equipment or additional power amplifiers.
2Reliability
If high power is used for jamming, then neutralization effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by modifying the synchronization pattern parameters (inserting dummy patterns with different timing or content) rather than increasing transmission power. This changes the jamming mechanism from power-based to information-based, achieving neutralization through signal confusion rather than overwhelming power.
Solution Approach 2:
The patent converts the terminal's own synchronization signals, which are normally useful for communication, into a harmful jamming tool. By inserting dummy synchronization patterns, the terminal transforms its beneficial communication capability into a deceptive signal that confuses receivers, achieving jamming without additional power expenditure.
3Use of energy by moving object
If simple jamming waveforms are used, then energy consumption is reduced, but detectability increases
Solution Approach 1:
The patent applies copying by creating dummy synchronization patterns that replicate the structure and appearance of legitimate synchronization signals. These copied patterns are inserted into the transmission stream, making the jamming signal indistinguishable from normal communication signals to receivers, thereby reducing detectability while consuming minimal energy.
Solution Approach 2:
The patent uses dummy synchronization patterns as an intermediary to achieve jamming. Rather than directly transmitting obvious jamming signals, the system inserts deceptive synchronization patterns that mediate between the transmitter and receiver, confusing the receiver's synchronization process without requiring high power or complex waveforms.
4Adaptability or versatility
If standard terminals are modified to jam, then adaptability is improved, but transmission chain modification is required
Solution Approach 1:
The patent applies preliminary action by generating dummy synchronization patterns at the data processing stage before signal transmission. The patterns are created and inserted into the data stream upstream in the transmission chain, allowing standard terminals to perform jamming without modifying the physical transmission hardware or power amplification stages.
Solution Approach 2:
The patent substitutes mechanical/hardware modifications with software/data-level operations. Instead of physically modifying the transmission chain hardware, the system uses data processing and signal generation techniques to insert dummy patterns, replacing complex hardware changes with simpler software-based solutions.

AI summary
A method for scrambling a communication system (EM,REC) consisting of generating, in a signal (S) intended to be transmitted by one or a plurality of transmitters (EM_B1, EM_B2,...,EM_B3) compatible with said communication system (EM,REC), at least one dummy sequence (SYNCF), said method being characterised in that it comprises the following steps: - Defining said dummy sequence (SYNCF) and the time and/or frequency position thereof within the signal (S) to be transmitted, - Estimating the value and the position of the dummy bits (BF) to be inserted into the data sequence (Du,T) to be transmitted at the input of the transmission chain or a sub-part of the transmission chain so as to obtain, in the sequence produced at the output of the transmission chain, the predefined value and time position of the symbols of said dummy sequence (SYNCF), - Inserting the dummy bits (BF) into said data sequence (Du,T), in the obtained positions.
