This exciting new book discusses the motivation for the evolution of a new breed of High Throughput Satellites (HTS) that have emerged from traditional communications satellites. It explores the commercial sectors and technical context that have shaped HTS. The historical underpinnings of HTS are provided to highlight the requirements that dimension these satellites. A survey of operational GEO HTS systems is also included. Readers will understand the technical, operational and commercial context of HTS systems, as well as the performance of the current HTS system. This initial breed of satellites was limited to geostationary satellites, but it is quickly projecting into low earth orbit (LEO...
This book constitutes the proceedings of the 9th International Conference on Wireless and Satellite Services, WiSATS 2017, held in Oxford, UK, in September 2017. The conference was formerly known as the International Conference on Personal Satellite Services (PSATS) mainly covering topics in the satellite domain. The aim of this conference is to bring together researchers, developers and practitioners from around the world in the field of wireless and satellite systems. The theme of WiSATS 2017 was on the means of using the wireless and satellite services directly to the user for personal communications, multimedia and location identification.
This book constitutes the thoroughly refereed post-conference proceedings of the Second International ICST Conference on Personal Satellite Services, PSATS 2010, held in Rome, Italy, Februray 2010. The conference included a keynote speech, 4 regular technical tracks and 4 special sessions consisting of 33 high-quality scientific papers. These cover various topics such as Satellite Communications: Coding and Modulations, Multimedia Integration, Satellite Network: Quality of Service and Architectures and Applications and Services, as well as Delay-Tolerant Networks, Quantum Satellite Communications, Access Quality Processing and Applications of Satellite Imagery.

Azumah Nelson has been described as the greatest boxer to come out of Africa. Born the year after his home nation of Ghana gained independence, he played a major part in putting this new country on the world map. A glittering amateur career saw him win every title except an Olympic medal, as Ghana boycotted the 1980 Games when he was a favourite to win. After turning professional, he took a last-minute bout for the world title with the great Salvador Sanchez, a bout that changed his life. Two years later, in 1984, he won the WBC Featherweight World Title. Like many champions, he rose from humble beginnings, suffered tragedy along the way, but he won and remained a world champion at featherweight and super featherweight for eleven years. Very few champions have carried such a burden of expectation, and Azumah delivered success at a time when his country needed a hero. He never faltered and won the respect of many across the world.

Helena tells Edward she is being forced to marry her stepbrother and that her stepfather is then planning to kill her to steal her wealth. She is also certain that her stepfather poisoned her mother. Vowing to save Helena, Edward enlists the help of trusted friends to fake Helena’s death. But events spiral out of control, and Edward is framed for a crime he didn’t commit. Edward realizes that his desire for love was too naïve in a world driven by lies, greed, and revenge. Will he be able to outsmart the top criminal minds in Malta to unite with Helena, or is Edward being used as a pawn?
Many wireless systems could benefit from the ability to transmit and receive on the same frequency at the same time, which is known as In-Band Full-Duplex (IBFD). This technology could lead to enhanced spectral efficiency for future wireless networks, such as fifth-generation New Radio (5G NR) and beyond, and could enable capabilities and applications that were previously considered impossible, such as IBFD with phased array systems. In this exciting new book, experts from industry, academic, and federal research institutions discuss the various approaches that can be taken to suppress the inherent self-interference that is generated in IBFD systems. Both static and adaptive techniques that ...
