Communication Jamming TRIZ Cases
- RF Interference Cancellation Using Beam and Omni Antennas
A beam antenna targets a jammer while an omnidirectional antenna captures signals for controller subtraction, achieving 70 to 75 dB cancellation efficacy.
- Anti-Spoofing Signal Subtraction for Navigation Reliability
Navigation devices generate spoofing signal replicas and subtract them from received radio frequency signals to isolate clean data streams.
- Antenna Side Lobe Modulation for Secure RF Communication
Amplitude modulating antenna side lobes encodes digital data to enable secure communication while minimizing interference with main lobe jamming signals.
- Broadcast Channel Control Loop for IoT Node Attack Mitigation
Management device relays attack-mitigation packets via intermediate nodes using a broadcast channel to reach compromised IoT network segments.
- Centralized Antijamming Matrix for Radar Signal Depollution
A centralized antijamming matrix calculates coefficients to generate multiple depolluted antenna channels from sub-network signals.
- Radio Jamming Detection via Network Intermediary Analysis
Network infrastructure detects intentional radio interference by analyzing terminal measurement reports.
- GNSS Jamming System Power Optimization
A jamming system uses linear modeling to calculate optimal interference power levels for individual jammers.
- Dynamic Jamming Power Control for Spatial Interference Limitation
A jamming device dynamically adjusts transmission power using sensor feedback to target specific communication signals.
- RFID Personal Data Protection Device with Signal Detection and Blocking
Personal data protection device detects carrier signals from RFID readers to activate a blocking mechanism that prevents unauthorized chip reading.
