The authors of this paper present their development and implementation of a cognitive radio (CR).


In this paper, the authors discuss their approach to developing and implementing a cognitive radio (CR), which is a transceiver that is aware, adaptive, and capable of learning. It may be visualized and realized as an intelligent software package (cognitive engine) controlling a software defined radio platform. The cognitive engine executes a set of nested loops constituting a cognition cycle, drawing on experience and stored knowledge to optimize a set of user-chosen quality of service measures. The process relies on the effectiveness of a set of tools that are individually well known but rarely found together: multi-objective genetic algorithms, case-based decision theory, and neural networks. Practical implementation problems include passing environmental information from the radio to the cognitive engine, acting on that information, and performing real-time control of the radio platform by the cognitive engine.
