A System View of Communications | HKUSTx on edX


When you start to build a house, you need a blueprint.
Otherwise, you wouldn’t know where
to start laying your bricks. In the same way, when you start
an electrical engineering curriculum, you need a blueprint. Think of each course as a brick. You need to know where each course fits into the overall scheme, so that your knowledge has
a strong foundation. I am Bert Shi, a Professor in the Department of Electronic and Computer Engineering at the Hong Kong University of Science and Technology. I am SH Song, also a Professor in the same department. This course “A System View
of Communications: From Signals to Packets” provides
that blueprint for you. It focuses on the mathematical aspects of the electronic engineering curriculum, including linear systems theory, probability theory, signal processing, and communication systems and networking. Our goal here is not to give you an in-depth account of these, but rather to show you how they fit together in the design and analysis of a wireless communication system, such as your mobile phone. The course is divided into three parts. In Part 1, we will discuss communication between a single sender and a receiver, like the remote control with your TV. In Part 2, we will look at how multiple senders and multiple receivers can share the same channel without interfering with each other, like a broadcast radio. In Part 3, we will explore how to transmit information over a network, like the Internet. We will discuss the fundamental limiting factors in design, the tools that engineers have developed to understand them, and simple techniques to address them. Important components of this course are online lab exercises, which are designed to build your intuition about these tools. Join us in this course, as we build your foundation for understanding the tools
and technologies used in communication. We hope you enjoy it.
