Description

Introduction by Prof. Tareq Al-Naffouri and Prof. Slim Alouini.;;Network information theory studies the fundamental limits of reliable transmission of information in multi-terminal systems. While network information theory has been around for 4 decades, only recently some major breakthroughs have illuminated the capacity of important settings such as the multi-antenna (vector) Gaussian broadcast channel, wireless relay networks with multi-source multicast and Gaussian interference channels. Most importantly, it has been realized that these information theoretic models and their corresponding fundamental limits characterization are not only intellectually challenging and fascinating problems, but have also a direct impact on the design of new generations of more and more efficient wireless systems. In fact, the intuition and guidelines derived from information theoretic results are playing an ever-growing prominent role in practical systems design.
