Multibeam Phased Array Antennas as Satellite Constellation Ground Station

The traditional reflector antennas are powerful but can only produce one beam once at a time. On the contrary, phased array antennas have the natural capability to produce multiple beams simultaneously, thus meeting the requirements for ordinary management and control of future satellite constellation. Compared to the reflector antennas, the architecture of phased array antennas are quite different with thousands of antenna elements, integrated transmit/receive (T/R) modules, decentralized power amplifiers, and agile beamforming networks. Furthermore, phased array antennas have many other advantages over reflector antennas, such as better performance, higher reliability, and lower cost. All of these make it a very attractive candidate as next generation LEO satellite constellation ground station.

Software Defined Radi. Enabling Technologies

Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communications. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability.SDR brings together two key technologies of the last decade - digital radio and downloadable software. It encompasses not only reconfiguration of the air interface parameters of handset and basestation products but also the whole mobile network, to facilitate the dynamic introduction of new functionality and mass-customised applications to the user's terminal, post-purchase.

Ultra Wideband Wireless Communication

This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer.Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues. System design elements, including channel modeling, coexistence, and interference mitigation and control* Review of MAC and network layer issues, up to the applicationCase studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks.Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.
