Course Objectives:

• 1. To understand the concepts of Cognitive Radio
• 2. To know the knowledge of Spectrum sensing
• 3. To manage the resources of spread spectrum communication system

Course Outcomes

At the end of this course, students will be able to:

• 1. Design a cognitive radio networks with understanding of spectrum sensing.
• 2. Develop the cognitive radio, as well as techniques for spectrum holes detection that cognitive radio takes advantages in order to exploit it.
• 3. Use efficiently TVWS for radio communications based on two spectrum sharing business models/policies.
• 4. Manage the radio-resources as well as a number of optimization techniques for better spectrum exploitation.
