Performance Analysis Of Energy Detector Over Different Generalised Wireless Channels Based Spectrum Sensing In Cognitive Radio

Spectrum Sensing for Cognitive Radio

This comprehensive reference text discusses concepts of cognitive radio and the advances in the field of spectrum sensing. This text discusses the concept of cognitive radio for next generation wireless communication and a very critical aspect of cognitive radio – that is, spectrum sensing – in detail. It covers important topics including narrowband spectrum sensing, wideband spectrum sensing, cooperative spectrum sensing, system and channel models, detection algorithms, approximation of decision statistics, and theoretical analysis of detection algorithms in detail. Separate chapters are dedicated to discussing the analysis and use of detection algorithms for narrowband spectrum sensing, wideband spectrum sensing, and cooperative wideband spectrum sensing. Aimed at graduate students and academic researchers in the fields of electrical engineering and electronics and communication engineering, this text: Discusses concepts of cognitive radio and research in spectrum sensing. Presents mathematical analysis of algorithms considering practical environment. Explains novel wideband spectrum sensing algorithms with detailed analysis. Provides mathematical derivations to help readers. Discusses basic spectrum sensing algorithms, from narrowband spectrum sensing to the more advanced wideband spectrum sensing.

Harvest of research outcomes to confirm achievement of the millennium development goals

In 2000, the leaders of member states of the United Nations adopted the Millennium Declaration, which set out a series of clear commitments, goals and targets to achieve Human Development. These ambitious goals were subsequently refined into eight Millennium Development Goals (MDGs), designed to provide a framework for accountability, donor coordination and resource mobilization. The MDGs are: Eradicate extreme poverty and hunger; achieve universal primary education; promote gender equality and empower women; reduce child mortality; improve maternal health; combat HIV/AIDS, malaria and other diseases; ensure environmental sustainability; and develop a global partnership for development. The first seven of these Goals are concerned with outcomes, identifying the progress towards certain standards of human well-being and decent living which should be achieved globally and nationally by 2015. The eighth Goal is concerned with relationships, identifying various aspects of a “global partnership for development” which must be forged to support the realization of these poverty reduction, human development and environmental sustainability standards. The MDGs provide opportunities to start working from real-life development problems. Addressing these problems requires multidisciplinary approaches that combine the natural sciences, the life sciences and technical approaches with social-science approaches. The challenge is to integrate social, economic, political and institutional concerns into research strategy. To be able to achieve this, there is a need to establish a linking pin between research, policy and practice in Nigeria. The aim of such a linking pin would be to synthesize research outcomes on specific MDGrelated topics and to translate these into implications for policy – and decision – making through easily accessible gathering where individual stakeholders can air their views. The articles contained in this book address research outcomes from stakeholders (Sociologists, Economists, Agronomists, Agricultural Engineers, Civil Engineers, Environmental Scientists and Engineers, Geographers, Geologists, Microbiologists, Medical Practitioners, Policy Makers, Educationists, etc.) to confirm achievement of Millennium Development Goals in Nigeria and other neighboring countries.
