Abstract:Robust, reliable, and interoperable wireless communication devices or technologies are vital to the success of positive train control (PTC) systems. Accordingly, the railway industry has started adopting software-defined radios (SDRs) for packet-data transmission. SDR systems realize previously fixed components as reconfigurable software. Recognizing the potential uses of SDRs for PTC systems, this project developed a railway cognitive radio (Rail-CR) that implements artificial intelligence decisionmaking capability in concert with an SDR to adapt to changing wireless conditions and learn from past experience. Objectives of the project included: developing a concept of operations for wireless data communication link adaptation based on use-case scenarios for packet radio systems; designing and implementing decisionmaking architecture on an SDR; designing strategies for radio environment observations; defining operational objectives and performance metrics; and designing and exercising a test plan to demonstrate performance under varying conditions.
