A System View of Communications: From Signals to Packets (Part 1)

The Hong Kong University of Science and Technology via edX


Have you ever wondered how information is transmitted using your mobile phone or a WiFi hotspot? This introductory course seeks to enable you to understand the basic engineering tools used and tradeoffs encountered in the design of these communication systems.

This course is divided into three parts. In Part 1, we examine the point-to-point link, which communicates information from a single transmitter to a single receiver. Part 2 examines how multiple transmitters can share the same physical channel. Part 3 discusses how information can be transmitted reliably from one station to another over a network that connects multiple stations. Online interactive exercises are included to help build your intuition.

This course was inspired by and built upon the course 6.02 Digital Communication Systems developed at MIT, which Prof Bertram Shi worked on during his sabbatical in 2009.

  • I thought the lectures were delivered in a very clear fashion and professor Bert Shi did a great job explaining the concepts starting with the basics. Staff was helpful in the discussion forums. The exercises were well designed and not too difficult (I perhaps would have liked some extra challenges) and the lab exercises (tiny programming exercises is Matlab) helped to better digest the material. I look forward to part 2 and 3 of the course.

    This course has good lecture, and good MATLAB test for understanding the communication engineering. There are a lot of important concepts, theories. I can't wait for the part 2.

    This was a very good course in system communications. The professors discussed some of the engineering tradeoffs and solutions in dealing w/ inter-symbol interference and noise. Course assessments included quizes after every lecture, matlab exercises involving simulating a communication system and a final. My only suggestion for improvement would be to provide some additional problems that are more involved than the ones found on the quizes that tie together different parts of the course.

    The explanation and illustration are very clear, detail and easy to follow for even communication-unrelated guy like me. I am grateful to have chance to take audit the course for broadening my knowledge. Thank you so much edX and HUST (prof. Shi and prof. Bart)

    The material was well explained and easy to understand. The power points were structured in very easy way to follow while slides being explained concisely.

    Excellent! All the concepts are clearly presented. The Labs and the use of Matlab complements the understanding of the contents. Thank you.
