This book constitutes the proceedings of the 8th International Conference on Wireless and Satellite Services, WiSATS 2016, held in Cardiff, UK, in September 2016. The conference was formerly known as the International Conference on Personal Satellite Services (PSATS) mainly covering topics in the satellite domain. As the scope of the conference widened to include wireless systems, the conference was renamed WiSATS. The 22 revised papers were selected from 32 submissions and cover a broad range of related state-of-the-art topics in antennas and mobile terminals, symbol precoding and network coding schemes, energy efficient strategies in satellite communication and cloud radio access networks, smart grid communication and optimization, security issues in vehicular ad-hoc networks (VANET) and delay tolerant net-works (DTN), interference mitigation in high throughput geostationary and non-geostationary satellite systems.

This book constitutes the proceedings of the 7th International Conference on Wireless and Satellite Services, WiSATS 2015, held in Bradford, UK, in July 2015. The conference was formerly known as the International Conference on Personal Satellite Services (PSATS) mainly covering topics in the satellite domain. As the scope of the conference widened to include wireless systems, the conference was renamed to WiSATS. The 29 revised papers were presented at the conference in three technical sessions and one special session on "Network Coding for Satellites". WiSATS 2015 also hosted two workshops along with the main conference: The first workshop, Communication Applications in Smart Grid (CASG 2015), focused on the merging area of using communication technology within the electricity power grid for smart monitoring and control. The second workshop, Advanced Next-Generation Broadband Satellite Systems (BSS 2015), focused on the use of satellite systems for providing next-generation broadband services.

The International Communications Satellite Systems Conference (ICSSC) is one of the most influential technical conferences in the field. The 36th edition was held in October 2018 in Niagara Falls, Canada. These proceedings present a broad spectrum of space communications topics from the conference, from the evolution of GEO from traditional area coverage to Ultra High Throughput Satellites (UHTS), the growing number of mega constellations expected to enter service in the next decade, navigation applications such as vehicle autonomy, wideband data backhaul from scientific and remote sensing payloads in LEO, and the extension of the 5G network to near earth, lunar and deep space environments in support of human exploration.

"Digital Communications: Principles and Systems" provides a thorough grounding in digital communications using an innovative engineering-first approach to build a nonmathematical overview covering building blocks, signal processing tasks, general features and design considerations. Topics covered include transmission channels, source coding, digital baseband transmission, digital modulation, noise impact in digital transmission, error control coding, advanced signal enhancement techniques for wireless channels and digital transmission link analysis and design.The reader is given an insight into the engineering concept and the underlying physical considerations, a clear appreciation of the parameters involved, and an understanding of the interplay of these parameters. The book includes several unpublished original derivations, new insights and alternative approaches that make the understanding of key topics and their application much easier.Topics covered include: * overview of digital communication* linear channels and systems* nonlinear systems* sampling of baseband and bandpass signals* quantization and PCM* source coding and lossless data compression* line codes* transmission through bandlimited AWGN channels* transmitted digital signals* noise impact in digital transmission* error control coding* digital transmission link analysis and designMany works on emerging digital transmission techniques are largely confined to academic research papers. This book will give postgraduate students and practicing engineers a sound mastery of the subject.

This book presents a broadband network designed with characterising propagation as well as networking issues to deliver communication services to a large population in remote areas. Long term rainfall data has been analysed to characterise attenuation level at a selected region such as Dhaka. Radar and rain gauge measurements at Sparsholt are also used to find rain cell size distribution, which is a crucial factor in site diversity implementation to combat severe rain fade. The network model is designed with dimensioning the effective bandwidth to support a number of users over the satellite link by taking into account the multimedia traffic characteristics. A robust coding scheme is implemented to improve the link quality to deliver broadband services. Different enhancement schemes are implemented to optimise TCP performance over satellite links. The book should be suitable for students at graduate/postgraduate level in Electronic Engineering in general, and Satellite Communications and Networking in particular. It is recommended for anyone who aspires to understand the concepts, structure, and elements of a broadband network.
