### Information Theory and Coding

The equation in the image above was published in the 1949 book "The Mathematical Theory of Communication", co-written by Claude Shannon and Warren Weaver. An elegant way to work out how efficient a code could be, it turned "information" from a vague word related to how much someone knew about something into a precise mathematical unit that could be measured, manipulated and transmitted. It was the start of the science of "information theory", a set of ideas that has allowed us to build the internet, digital computers and telecommunications systems. When anyone talks about the information revolution of the last few decades, it is Shannon's idea of the information that they are talking about. [ref]

We at SPCRC are working on latest developments in coding theory which would have broad applications in the future signal processing and communication domain.
