Advances in Communication Systems: Theory and Applications, Volume 4 is a compilation of review articles and papers on advances in communication systems.

This volume contains contributions on the application of information-theoretic concepts to real communication channels such as feedback decoding, channel equalization, and coded modulation for certain non-coherent channels. Data compression, advances in broadcast channels, and optical fiber technology are also discussed.

Communications systems engineers will find the book interesting.
