What Is Communications?
In the broadest context, communications is the study of techniques to allow for the reliable transmission of information.
The information we are dealing with can take many different forms. It may be the conversation you are having on your cell phone, the web page you have just downloaded, the data stored on your hard-disk, or the latest motion picture released on digital media. All these types of information have in common the requirement that they be transferred from one place (or time) to another. The purpose of our group is to study efficient ways of achieving this task.
In order to design a communications system, techniques must be developed which allow for the reliable, secure, and speedy delivery of the data. Mathematics is a central tool used to perform the design and analysis of these techniques. The communications system designer often creates a mathematical model of the system along with the requirements. Techniques are then developed to satisfy the requirements while minimizing the cost. Computer simulation and experimental test beds may be developed to generate additional insights. They are often used to validate and optimize the design before its deployment.Some of the principal questions that the discipline of communications aims to answer are:
A Bit about the History of Communications
Communication is one of the most essential aspects to the advancement and development of civilization as we know it today. The beginning of verbal communication is estimated to be over 50,000 years ago. Graphic images over 20,000 years old have been found in caves, and written records over 5,000 years old have also been discovered!
The following list includes a selected number of more recent milestones. If you are studying in the area of electrical or computer engineering or a related discipline you will most definitely recognize many of the names and ideas mentioned below.
