Personal Wireless Communications
There are numerous factors contributing to the dynamic growth of wireless communication systems we've been observing in the past 10 years, the most important being the increasing network user mobility and the technological advances in high-speed data transmission over radio channels. Research centres and standards-making institutions the world over conduct works on 3G integrated systems of person-to-person and person-to-computer communications, wireless counterparts of classical LAN, ATM and IP architectures, satellite and access networks as well as advanced service platforms like W AP and other concepts. Among the many commercial and non-profit organisations professionally involved in the d...
Reliving the memories of an Indian forester: Memoir of S Shyam Sunder
Shyam Sunder’s education, in Mangalore and later in Madras, followed a course predestined for entry in to the forest service. In the Madras Presidency of the early 1950s, selection to a Class I government post was highly coveted, as well as restricted by numerous fences of exclusion. However, he succeeded due to several unusual events he narrates vividly in this memoir. One of his early forestry mentors cautioned, “Shyam Sunder, you’ll either go very far or will lose your way. I advise you to be careful.” As a researcher, forest administrator, and later as head of the forest department, he always chose to do what felt right. Inexplicably, that hastened success throughout his career. ...
Animal Biodiversity: Patterns and Process
India being one of the top twelve mega biodiversity countries in the world, the increasing rate of erosion of biodiversity has been causing great concern. Because of socio-economic changes, biological diversity has to come to occupying the central stage as it holds `key to the maintenance of the world'. Biodiversity is a multifactered science bringing the ecologist and environmentalist together resulting in an interdisciplinary subject. Issues like ecosystem dynamics, global changes and impact of the loss of biodiversity at various level such as local, national and global levels have become important. As a result of the loss of increasingly recognised. The need to understand traditional ecological knowledge for managing biodiversity by the local people has also come to be appreciated. The book therefore, attempts to provide an overall emphasis of diverse aspects of animal biodiversity, including soil, vectors of animal and plant diseases, agroecosystem diversity, forest biodiversity, marine, fresh water and island biodiversity. The impact of taxonomy, biotechnology and remote sensing, besides the conservation and management of biodiversity has also been briefly discussed.
An Introduction to Passive Radar, Second Edition
This bestselling book – now in its second edition – introduces the basic principles of passive radar technology and provides a comprehensive overview of the recent developments and advances in this field. It shows you how passive radar works, how it differs from the active type, and helps you understand the benefits and drawbacks of this novel technology. The book gives you the knowledge you need to get a full understanding of this fascinating technology. All chapters have been fully revised and updated and are written in a clear and accessible style. New chapters have been added to cover advances in the technology that have already been built and demonstrated, including systems on moving platforms (aircraft and UAVs), as well as advances in types of transmission – notably single-frequency broadcast transmissions, and 5G – and in processing techniques. This book remains an important resource for engineers working in academic, industry, or government research laboratories; academics teaching graduate level students; and those working in the specification and procurement of radar systems who need to understand the performance and limitations of the technology.
Mobile and Wireless Communications
Mobile and Wireless Communications presents the latest developments in mobile and wireless research and the industry, with a broad range of topics including: -Ad-hoc networking; -Power control; -Personal communications; -Satellite; -QoS; -UMTS and wireless LANs; -Handoffs, security and mobility; -CDMA and physical layer including modulation and coding; -Methods of communication functions including multiple access, error control, flow control and routing. This state-of-the-art volume comprises the edited proceedings of the Working Conference on Personal Wireless Communications (PWC'2002), which was sponsored by the International Federation for Information Processing (IFIP), organized by IFIP Working Group 6.8, and held in Singapore in October 2002.
Monopulse Radar Theory and Practice, Second Edition
Monopulse is a type of radar that sends additional information in the signal in order to avoid problems caused by rapid changes in signal strength. Monopulse is resistant to jamming which is one of the main reasons it is used in most radar systems today. This updated and expanded edition of an Artech House classic offers you a current and comprehensive treatment of monopulse radar principles, techniques, and applications. The Second Edition features two brand new chapters, covering monopulse countermeasures and counter-countermeasures and monopulse for airborne radar and homing seekers. This essential volume categorizes and describes the various forms of monopulse radar, and analyzes their capabilities and limitations. The book also devotes considerable space to monopulse circuits and hardware components, explaining their functions and performance. This practical resource features numerous photographs and illustrations drawn from actual radar systems and components. This book serves as a valuable reference for both experienced radar engineers and those new to the field.
The Micro-doppler Effect in Radar
The Doppler Effect can be thought of as the change in frequency of a wave for an observer moving relative to the source of the wave. In radar, it is used to measure the velocity of detected objects. This highly practical resource provides thorough working knowledge of the micro-Doppler effect in radar, including its principles, applications and implementation with MATLAB codes. The book presents code for simulating radar backscattering from targets with various motions, generating micro-Doppler signatures, and analyzing the characteristics of targets. In this title, professionals will find detailed descriptions of the physics and mathematics of the Doppler and micro-Doppler effect. The book provides a wide range of clear examples, including an oscillating pendulum, a spinning and precession heavy top, rotating rotor blades of a helicopter, rotating wind-turbine blades, a person walking with swinging arms and legs, a flying bird, and movements of quadruped animals.
Emerging Personal Wireless Communications
The growth of telecommunications has been largely based on mobile and data services in the past 10 years and the growth will continue. For instance, it is forecasted that after 2005 the mobile traffic turnover in Europe will exceed that of fixed telephone traffic and the penetration of Internet access through mobile will exceed that of fixed access. It is expected that the new value added services will be Internet-based and the IP traffic will outweigh the amount of traditional ISDN based telephone traffic. The transition from the existing telecommunications services to mobile and Internet based ones will change the service infrastructure as well as the customer and service management struct...
