This welcome second edition to the 2002 original presents the logical arithmetical or computational procedures within communications systems that will ensure the solution to various problems. The authors comprehensively introduce the theoretical elements which are at the basis of the field of algorithms for communications systems. Various applications of these algorithms are then illustrated with a focus on wired and wireless network access technologies. The updated applications will focus on 5G standards, and new material will include MIMO systems (Space-time block coding / Spatial multiplexing / Beamforming and interference management / Channel Estimation /mmWave Model); OFDM and SC-FDMA (Synchronization / Resource allocation (bit and power loading) / Filtered OFDM); Full Duplex Systems (Digital interference cancellation techniques).

Addressing the fundamental technologies and theories associated with designing complex communications systems and networks, "Principles of Communications Networks and Systems" provides models and analytical methods for evaluating their performance. Including both the physical layer (digital transmission and modulation) and networking topics, the quality of service concepts belonging to the different layers of the protocol stack are interrelated to form a comprehensive picture.

The book is designed to present the material in an accessible but rigorous manner. It jointly addresses networking and transmission aspects following a unified approach and using a bottom up style of presentation, starting from requirements on transmission links all the way up to the corresponding quality of service at network and application layers. The focus is on presenting the material in an integrated and systematic fashion so that students will have a clear view of all the principal aspects and of how they interconnect with each other.

A comprehensive introduction to communications systems and networks, addressing both network and transmission topicsStructured for effective learning, with basic principles and technologies being introduced before more advanced ones are explainedFeatures examples of existing systems and recent standards as well as advanced digital modulation techniques such as CDMA and OFDMContains tools to help the reader in the design and performance analysis of modern communications systemsProvides problems at the end of each chapter, with answers on an accompanying website
