INTERFERENCE DETECTION AND REJECTION IN A COMMUNICATION/NAVIGATION NARROWBAND AND WIDEBAND RADIO - A simplified explanation of the abstract
This abstract first appeared for US patent application 18052126 titled 'INTERFERENCE DETECTION AND REJECTION IN A COMMUNICATION/NAVIGATION NARROWBAND AND WIDEBAND RADIO
Simplified Explanation
The system described in the patent application is a radio receiver with tunable RF notch filters that can receive a desired RF signal while rejecting interference signals. Here are some key points to explain the innovation:
- The system includes a splitter that divides the received RF signal into a main signal path and an interference detection path.
- The interference detection path consists of a mixer, a synthesizer, and a SAW filter to improve the accuracy of detecting interference frequencies.
- The processor estimates the interference frequency based on the detected signal samples and synthesizer tuned frequency.
- If the detected interference signal exceeds a threshold, the processor sends a control signal to configure the notch filters at the interference frequency.
Potential Applications
This technology could be applied in various industries where radio receivers are used, such as telecommunications, broadcasting, and radar systems.
Problems Solved
This system addresses the issue of interference signals disrupting the reception of desired RF signals, leading to improved signal quality and reliability.
Benefits
The system enhances the accuracy and resolution of detecting interference frequencies, leading to better overall performance of the radio receiver.
Potential Commercial Applications
Potential commercial applications of this technology include the development of advanced radio receivers for military communications, satellite systems, and wireless networks.
Possible Prior Art
One possible prior art for this technology could be the use of SAW filters in radio receivers to improve signal filtering and interference rejection.
Unanswered Questions
How does the system handle multiple interference signals at different frequencies?
The system is designed to detect and reject interference signals based on their frequencies. If there are multiple interference signals at different frequencies, the processor may need to prioritize and address them based on their amplitudes and impact on the desired RF signal.
Can the system adapt to changing interference patterns in real-time?
The system's processor is capable of estimating interference frequencies and configuring the notch filters accordingly. However, the system's ability to adapt to rapidly changing interference patterns in real-time may depend on the speed and efficiency of the processor and other components.
Original Abstract Submitted
A system comprises a radio receiver including an antenna, tunable RF notch filters that receive a desired RF signal and reject an interference signal, a LNA, a splitter, and a processor. A received RF signal is divided by the splitter and directed along a main signal path and an interference detection path. The interference detection path comprises a mixer that converts the received RF signal to an IF band, a synthesizer, and a SAW filter in communication with the mixer. The SAW filter rejects any IF signal generated due to a desired received RF signal and improves an accuracy/resolution of a detected interference frequency. The processor estimates the interference frequency based on a detected amplitude of signal samples and a synthesizer tuned frequency for that amplitude. If the detected amplitude is more than a threshold, then a control signal is sent to configure the notch filters at the interference frequency.
