EE-635 Advanced Topics in Communication Systems 3-0-0-6

In recent years, the field of communication engineering has seen tremendous growth. Wireless communications is one of the fastest growing segments of the communication industry. The increasing demand for wider bandwidth has motivated development and introduction of some key technologies in the area of wireless communication. The objective of this course is to introduce the students to some of these latest developments in the area of wireless communication. This course will also provide foundation for carrying out research in these emerging areas.
