Course Description

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 completed this course including the exercises with a score of 77% and I liked it very much, because I learnt a lot of interesting things with little effort. In fact, this course is rather short compared to a real university lecture, but it contains all the important key facts. For me, it was perfect to follow this course in the evenings after my regular day job. Everything is explained very slowly and easy understandably, except for some math. To understand this course you should therefore bring some math knowledge on a beginning university level.

I completed the course with a final score of 77% and found every week of the course interesting but I feel that I did not completely understand a lot of the content. Video lectures are well produced and clearly explained -- about 60 minutes each week, broken into 5-10 minute blocks, with a PDF file also available containing all the formulas that are used in each lecture. This is followed by quiz questions and online MATLAB exercises. The first two weeks were straight-forward. Then the course became very difficult with a lot of trigonometry and complex numbers, moving forward at a fast pace and I had trouble fully understanding all the concepts. The online discussion forum was not very active, so there was not much help there. The final week was an exam which I found very difficult and some questions I simply could not answer.
