Digital Communication I: Modulation and Coding Course-Lecture 1

Communications is a process by which information is exchanged between individuals through a common system of symbols, signs, or behaviour “It is about communication between people; the rest is technology” Communication systems are reliable, economical and efficient means of communications Public switched telephone network (PSTN), mobile telephone communication (GSM, 3G, 4G.), broadcast radio or television, navigation systems, . The course is aiming at introducing fundamental issues required for understanding and designing a (digital) communication system. | Digital Communication I: Modulation and Coding Course Term 3 - 2009 Lecture 1 Lecture 1 Course information Scope of the course Digital Communication systems Practical information Course material Lay-out of the course in terms of Lectures, Tutorials, Lab assignment, Exam Staff More detailed information on the lab Lay-out of the course indicating which parts of the course are easier/more difficult.
