Description: A Survey of Spectrum Sensing Algorithms The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts. It is one of the most challenging issues in cognitive radio systems. In this paper, a survey of spectrum sensing methodologies for cognitive radio is presented. Various aspects of spectrum sensing problem are studied from a cognitive radio perspective and multi-dimensional spectrum sensing concept is introduced. Challenges associated with spectrum sensing are given and enabling spectrum sensing methods are reviewed. The paper explains the cooperative sensing concept and its various forms. External sensing algorithms and other alternative sensing methods are discussed. Furthermore, statistical modeling of network traffic and utilization of these models for prediction of primary user behavior is studied. Finally, sensing features of some current wireless standards are given. Platform: |

Description: 基于能量检测的频谱感知.由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。-spectrum sensing in cognitive radio based on energy detection.As the channels in diameter and shadow, not a single user spectrum of capabilities and therefore need different between a user to the spectrum is perceived as more and the effect. this design for the use of a coordination mechanism, the two users collaborate spectrum, the detection rate of increase and decrease the test of time and get a change requires immediate gain. some emulation.

Description: This book is primarily designed for senior undergraduate students, postgraduates,
researchers, and industry personnel working in the areas of signal processing, nextgeneration wireless communication, and detection and estimation. The book will
introduce readers to cognitive radio and the recent research in its main functionality,
that is, spectrum sensing. The cognitive radio is the essential enabling technology for
next-generation wireless communication like 5G and beyond. It guides the readers
from the basic spectrum sensing algorithm for narrowband spectrum sensing to the
more advanced wideband spectrum sensing, including cooperative sensing. In addition to that, the book discusses practical issues associated with implementing them
in practice, like fading and noise uncertainty. Each chapter is equipped with rich
mathematical proofs and derivations. We have also added appendices to help readers
understand and derive the equations used in different chapters of the book. Platform: |

Description: Spectrum sensing is critically important for cognitive radio, an emerging solution
to the spectrum congestion and low usage of licensed spectrum. Energy detection
is a promising low-complexity and low-cost spectrum sensing technique. Its
performance analysis has been revisited extensively in the recent literature. This
book thus aims at a comprehensive summary of recent research on energy detection
for spectrum sensing in cognitive radio networks. This book is for researchers
and engineers in both industry and academia who would like to know more about
applications of energy detection.
