This book is an efficient introduction to fundamental concepts and principles underlying the behavior of queueing systems and its application to the design of packet-oriented electrical communication systems. In addition to techniques and approaches found in earlier works, the author presents a thoroughly modern computational approach based on Schur decomposition. This approach facilitates solution of broad classes of problems wherein a number of practical modeling issues may be explored.

…very comprehensive and covers the entire topic of Raman amplification as applied to communication systems. As befitting a book of this length, the treatment is exhaustive and provides a range of information, from historical perspective, to current implementations, to some forecasts of important technologies for the future.
Raman Amplification in Fiber Optical Communication Systems is an excellent book to fully understand how this cutting-edge technology works…In brief, I highly recommend reading this book. - Bertrand Desthieux, Editor-in-Chief of Optical Fiber Technology.

The capacity of wireless data communications is lagging behind demands due to unsatisfactory performance of the existing wireless networks, such as low data rates, low spectral efficiency and low quality of service. Space-time coding is an effective transmit diversity technique to combat fading in wireless communications.
Space-time codes are a highly bandwidth-efficient approach to signalling within wireless communication that takes advantage of the spatial dimension by transmitting a number of data streams using multiple co-located antennas. There are various approaches to the coding structures, including space-time trellis coded modulation, space-time turbo codes and also layered architectures. The central issue in all these various coding structures is the exploitation of multipath effects in order to achieve very high spectral efficiencies.
