A Broadband Apparatus for Underserviced Remote Communities: Connecting the Unconnected (Southern Space Studies)

by Christoffel Kotze

This book investigates how broadband internet can be provided to remote and isolated communities through the use of satellite and other enabling technologies, in the form of a self-contained broadband apparatus. It discusses how the proposed design can help bridge the digital divide by removing one of the main hurdles to adopting technologies: infrastructure. In turn, the book explores how the lack of infrastructure, especially with regard to connectivity and electricity, can be addressed by exploiting new technological advances in a number of fields, notably the newly proposed large broadband satellite constellations. In closing, it uses concrete examples to demonstrate the potential positive impacts of a “broadband ecosystem” on economics, governance and society, and on achieving the United Nations’ Sustainable Development Goals.

Broadband Array Processing (Springer Topics in Signal Processing #17)

by Shefeng Yan

This book describes the background and technology of array signal modeling. It presents the concept and formulation of beamformers and discusses several commonly used array performance measures. It also introduces two traditional types of beamformers: delay-and-sum and optimum beamformers.Chapter 1 includes background information on array processing, while Chapters 2 and 3 discuss the DFT-based frequency-domain implementation of a broadband beamformer and the design of subband beamformers for frequency-domain broadband beamformers. Chapter 4 presents the FIR-based, time-domain implementation of the broadband beamformer, where the FIR beamformer is designed by separately designing the subband beamformers and the corresponding FIR filters. The techniques for optimal design of the FIR beamformer are developed in Chapter 5, and Chapters 6 and 7 focus on the modal beamforming problem for circular arrays for the frequency-domain modal beamformer and the time-domain modal beamformer. Lastly, the final chapters present frequency-domain and time-domain modal beamformers for spherical arrays.

Broadband as a Video Platform: Strategies for Africa (The Economics of Information, Communication, and Entertainment)

by Eli M. Noam Judith O'Neill Darcy Gerbarg

This volume features contributions from a conference held in Lusaka, Zambia, to explore the role and prospects of broadband in Africa as a video platform--with emphasis on the strategies and building blocks for deployment and advancement. While it may seem that such networks and their applications are not a realistic scenario for developing countries, it would be short-sighted and economically dangerous to ignore the emerging trends. The pace of introduction of next-generation networks in industrialized countries is rapid and the developing world will not be able to stand aside. The risks of falling behind are great and in any country there will be elements of business and society who wish to forge ahead. Policymakers and network architects need to be prepared. Media companies and broadcasters, in particular, must be alert to the new developments as should be medical and educational institutions. The availability of advanced high-speed business application tools in a country will affect its participation in international transactions and its economic growth. This volume features contributions from industry leaders, policymakers and scholars, representing a variety of perspectives, including technology and infrastructure management, economic development, marketing, education and health. The authors collectively discuss how broadband deployment as a platform with sufficient speed for video may be encouraged by public policy and regulation and how investment in broadband for this and related purposes can improve the quality of life and experience in Sub Saharan Africa in media and data, while being a financeable, commercially sound business.

Broadband Direct RF Digitization Receivers (Analog Circuits and Signal Processing #121)

by Olivier Jamin

This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains. A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis. Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm CMOS processes, together with the block and system-level measurement results. Readers will benefit from the techniques presented, which are highly competitive, both in terms of cost and RF performance, while drastically reducing power consumption.

Broadband for Africa: Developing Backbone Communications Networks in the Region

by Mark D. Williams

Many countries in Sub-Saharan Africa see broadband ICT as an essential part of their long-term economic development strategy. Backbone networks are the high-capacity networks that lie at the heart of communications systems and allow the delivery of the high volumes of data needed for broadband. What high-capacity backbone networks that do exist in the region are typically limited to major urban areas and some inter-city routes. Competition between backbone networks is underdeveloped so the price of services remains high and quality is often poor. This pattern of network development is the result of high costs and regulatory restrictions on network development. Where countries have fully liberalized their telecommunications markets and promoted infrastructure competition, prices have fallen and quality improved. Backbone network policy should focus on promoting competition, reducing the cost of network construction and encouraging network development into currently underserved areas. Competition can be promoted by removing regulatory restrictions such as limits on the number of licenses and constraints on type of infrastructure and services that licensees can offer. The cost of backbone network development can be reduced by utilizing energy and transport infrastructure and reducing legal costs such as obtaining planning permission. Stimulating backbone network development beyond major urban areas can be achieved through establishing public-private partnerships to encourage operators to build networks into currently underserved areas.

Broadcasting Fidelity: German Radio and the Rise of Early Electronic Music

by Myles W. Jackson

A landmark history of early radio in Germany and the quest for broadcast fidelityWhen we turn on a radio or stream a playlist, we can usually recognize the instrument we hear, whether it&’s a cello, a guitar, or an operatic voice. Such fidelity was not always true of radio. Broadcasting Fidelity shows how the problem of broadcast fidelity pushed German scientists beyond the traditional bounds of their disciplines and led to the creation of one of the most important electronic instruments of the twentieth century.In the early days of radio, acoustical distortions made it hard for even the most discerning musical ears to differentiate instruments and voices. The physicists and engineers of interwar Germany, with the assistance of leading composers and musicians, tackled this daunting technical challenge. Research led to the invention in 1930 of the trautonium, an early electronic instrument capable of imitating the timbres of numerous acoustical instruments and generating novel sounds for many musical genres. Myles Jackson charts the broader political and artistic trajectories of this instrument, tracing how it was embraced by the Nazis and subsequently used to subvert Nazi aesthetics after the war and describing how Alfred Hitchcock commissioned a later version of the trautonium to provide the sounds of birds squawking and flapping their wings in his 1963 thriller The Birds.A splendid work of scholarship by an acclaimed historian of science, Broadcasting Fidelity reveals how the interplay of science, technology, politics, and culture gave rise to new aesthetic concepts, innovative musical genres, and the modern discipline of electroacoustics.

Broadening the Genetic Base of Grain Cereals

by Sandeep Kumar Mohar Singh

This book offers comprehensive coverage of important grain cereals including their origin and distribution, crop gene pool, level of diversity, production constraints, traits of importance for genetic base widening, crop improvement methodologies, genome mapping, genomics for breeding, and future strategies. The chapters, contributed by eminent crop researchers from around the world, provide rare insights into the crop-specific constraints and prospects drawing from their substantial experience. As such, the book offers an essential source of information for grain cereals scientists, teachers, students, policy planners and developmental experts alike. Grain cereals, which comprise rice, wheat, maize, barley, oats, sorghum and millets, are members of the grass family. These crops are vital to human nutrition, thanks to their roles as staple food crops in different parts of the globe. Some of them are rich sources of carbohydrates, which provide energy, while others are important sources of minerals, vitamins and proteins, in addition to their medicinal properties. In most cereals, the existing variability among elite germplasm has been exploited to attain a desirable level of productivity. However, to make further breakthroughs in enhancing yield and improving stability in future crop cultivars, new sources of genes/alleles need to be identified in wild/weedy species and incorporated into the cultivated varieties. Though there have been many publications on various aspects of grain cereal improvement in the recent past, to date this essential information has remained scattered among different periodicals.
