Cognitive Radios, Networks and Systems for Digital Communications

This seminar provides a tutorial on multiple cognitive functions and capabilities at multiple levels including an overall cognitive system approach to reduce the effects of the environment. It covers a wide range of cognitive techniques, including cognitive radios, dynamic spectrum access DSA, adaptive power control using control theory for stability, adaptive modulation, adaptive spreading and error correction, dynamic antenna techniques using AESAs, cognitive antennas and MIMO, adaptive filters, orthogonalizing techniques, cognitive re-configuration of networks including mesh and Adhoc networks, optimizing networks, learning and reasoning techniques for cognitive decisions, goal conflicts, and cognitive system approach utilizing all available adaptive and controllable capabilities in the system. In addition, several examples and step processes are discussed to determine the optimal solutions and tradeoffs between the many cognitive capabilities.
