Frequency Assignment and Network Planning for Digital Terrestrial Broadcasting Systems


Book Description

Frequency Assignment and Network Planning for Digital Terrestrial Broadcasting Systems focuses on Digital Audio Broadcasting and Digital Video Broadcasting. The author provides a concise introduction to the subject and presents principles, concepts and commonly accepted methods used in the planning process. The frequency assignment material focuses on allotment planning while network planning is dealt with mainly from a network optimization perspective. All methods introduced and mathematical tools presented are fully explained. General concepts are illustrated with the help of several planning scenarios both for frequency assignment and network planning. Frequency assignment and network planning are vital issues throughout most of Europe and North America as a direct consequence of the increasing demand for digital communication systems.




A Strategy for Active Remote Sensing Amid Increased Demand for Radio Spectrum


Book Description

Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.
