This course enables students to have basic techniques to design wireless communication systems such as wireless LANs and cellular systems as in our daily lives. By picking up IEEE802.11a as a representative of modern wireless communication system, the course gives details about technologies used in the system such as interference management, diversity combining, and multiplexing. At the end of the course, students will be able to understand the design concept, transceiver architecture, role of components, and specifications of IEEE802.11a wireless LAN.
In the class, advanced knowledge on channel propagation, modulation/demodulation, diversity combining, error correction coding, adaptive modulation coding, adaptive equalizer, spread spectrum, orthogonal frequency multiplexing, array signal processing, and MIMO multiplexing are lectured and all of them are mandatory technologies for modern wireless communication systems.
By the end of this course, students will be able to:
1) Design link budget of wireless communication systems at given environments.
2) Understand transceiver architecture and its specifications of modern wireless LANs and cellular systems.
3) Describe wireless communication systems mathematically by utilizing Fourier transform and applied probability and statistics
4) Understand general technologies for interference, channel fading, and multiplexing used in modern wireless communication systems.
