Comb Filter Software Defined Radio Stabilization Technique for 10 GHz

Participation details: Anytime, anywhere, project has a target schedule


This project implements design approaches discussed by Tom Clark K3IO and Kerry Banke N6IZW, where an injected local signal is used to stabilize a 10 GHz downlink signal received by a dish antenna.
Higher frequency digital communications generally require an increase in the quality of the clock signals in the radio. Attempting to receive without sufficient clock performance results in loss of data or the inability to receive a signal at all. There are multiple ways to specify clock signal quality, with phase noise being of special interest. Here, we want to use a known stable signal to correct a particular type of received signal.
This project will research, document, and simulate the proposed technique.
After review, the student will write code that simulates the technique under worst case conditions. What are the limits of this technique? Can machine learning be applied? Can the technique be adaptive or automated? What are the failure modes? How can those be prevented with software? What is required to deploy the code as a reference design in GNU Radio?
A mathematical background and basic understanding of digital signal processing is helpful but not required.

Open Research Institute commits to enable and support any volunteer wishing to contribute to this project.
