1Reliability
If existing jamming suppression methods are used, then jamming signals can be suppressed, but the methods are limited in adaptability and practicality due to equipment constraints
Solution Approach 1:
The patent implements a universal jamming suppression system that can operate with different types of radio-frequency transmitters and receivers through standardized signal processing interfaces. The cancellation signal generator processes jamming signals and generates appropriate cancellation signals that can be applied across multiple equipment types, making the system adaptable to various military and intelligence operations without requiring equipment-specific customized solutions.
2Reliability
If existing jamming suppression methods are used, then jamming signals can be suppressed, but implementation becomes impractical in certain locations or operations
Solution Approach 1:
The system automatically detects jamming signals, processes them through the cancellation signal generator, and applies suppression without requiring manual intervention or complex setup. The feedback mechanism allows the system to self-adjust and optimize performance in real-time, making it practical to deploy in various locations and operations without extensive preparation or specialized operational procedures.
3Reliability
If jamming signals are suppressed using existing methods, then communications can be enabled, but the system complexity increases
Solution Approach 1:
The patent extracts the jamming signal suppression function from the main communication system by implementing a dedicated cancellation signal generator that operates independently. This modular approach allows the suppression functionality to be added as a separate module that interfaces with existing transmitters and receivers, avoiding the need to redesign the entire communication system while still achieving effective jamming suppression.

AI summary
Provided are processes for suppressing jamming signals that may include use of a signal processing circuit. A signal processing circuit can be configured to obtain a jamming signal and a feedback signal, process the jamming signal and the feedback signal to determine a cancellation signal for use in suppressing the jamming signal, and output the cancellation signal to a radio-frequency transmitter. The signal processing circuit may be further configured to obtain a transmission signal, determine a jamming channel from the jamming signal and a feedback channel from the feedback signal, and combine the transmission channel, jamming channel, and feedback channel to determine a transfer function, where the transfer function is configured to determine the cancellation signal.
