MP3 stands for Moving Picture Experts Group 1 layer 3. It is a standard for compressed audio files based on psychoacoustic models of human hearing. By means of masking time and frequency, limiting bandwidth and Huffman coding, it allows one to reduce the amount of information needed to represent an audio signal,

This chapter introduces some of the basic concepts of information theory, as well as the definitions and notations of We shall often use the shorthand pdf for the probability density func- tion pX(x).

The basic problem of coding theory is that of communication over an unreliable channel that results in errors . Restating what we have discussed above, the aim of coding theory is to construct a code with a short n, the intuition that the information gained by seeing a symbol ai that is sent with probability pi should be.
The course will study how information is measured in terms of probability and entropy, and the relationships among conditional and joint entropies; how these are used to calculate the capacity of a communication channel, with and without noise; coding schemes, including error correcting codes; how discrete channels and
6 Jan 2016 Information theory is the science of operations on data such as compression, storage, and com- munication. It is among the few disciplines fortunate to have a precise date of birth: 1948, with the publication of Claude E. Shannon's paper entitled A Mathematical Theory of Communication. Shannon's
Interactive information and coding theory. Mark Braverman?. Abstract. We give a high-level overview of recent developments in interactive informa- tion and coding theory. These include developments involving interactive noiseless coding and interactive error-correction. The overview is primarily focused on developments

In the present book very little attention is paid to the relation between coding theory and combina- torial mathematics. For this the reader should consult PJ. Cameron and. J.H. van Lint
structure: information can be combined or aggregated, information must be focussed on specified questions. This important aspect however is not treated in depth. This will be reserved to other modules. The same holds true for the application of classical information theory to coding, communication and other domains.
