Brief summary

From the earliest beginnings of message transmission as an engineering discipline,  it has been the endeavour of many engineers and mathematicians  to find a quantitative measure for the

  • contained  $\rm information$  $($quite generally:  "the knowledge about something"$)$
  • in a  $\rm message$  $($here we mean  "a collection of symbols and/or states"$)$.


The  $($abstract$)$  information is communicated by the  $($concrete$)$  message and can be conceived as the interpretation of a message.

Claude Elwood Shannon  succeeded in 1948,  in establishing a consistent theory about the information content of messages,  which was revolutionary in its time and created a new,  still highly topical field of science:  »Shannon's information theory«  named after him.» KORREKTUR: »?

This is what the fourth book in the  $\rm LNTww$ series deals with,  in particular:

  1. Entropy of discrete-value sources with and withott memory,  as well as natural message sources:  Definition,  meaning and computational possibilities.
  2. Source coding and data compression,  especially the   "Lempel–Ziv–Welch method"   and   "Huffman's entropy encoding".
  3. Various entropies of two-dimensional discrete-value random quantities.  Mutual information and channel capacity.  Application to digital signal transmission.
  4. Discrete-value information theory.  Differential entropy.  AWGN channel capacity with continuous-valued as well as discrete-valued input.
