Cooperative Spectrum Sensing Technique
2007 International Conference on Wireless Communications, Networking and Mobile Computing, 2007Cognitive Radios (CRs), which sense the spectrum and implement opportunistic sharing when no licensed user is found to use it, are able to improve the efficiency of spectrum. Spectrum sensing must be firstly solved in CRs. Cooperative sensing can make good use of network resources, obtain higher gain and make the network steadier. In this paper we give

Cognitive radio has come a long way in the recent years with the advent of improved algorithms and instrumentation. However, for ease and efficient working of cognitive radio, there is a need to have effective detection of spectrum sensing. The objective of spectrum sensing techniques is to find spectrum holes which can be accessible by the users of ...

Spectrum Awareness: Techniques and Challenges for Active Spectrum Sensing
2007Radio spectrum is not efficiently used, mainly due to the prevailing rigid frequency allocation policy. Only some bands of the spectrum - such as those bands used by cellular base stations - are heavily used. Many bands are not used at all or are used only part of the time.

Multiplatform Spectrum Sensing Prototype
2018 IEEE 61st International Midwest Symposium on Circuits and Systems (MWSCAS), 2018Smart spectrum sharing initiatives have been stimulated by the spectrum scarcity experienced nowadays. The option that secondary users may access idle channels avoiding harmful interferences to primary users is a viable option to alleviate the spectrum crunch.

Robust Compressive Spectrum Sensing
2018In this chapter, the existing work on compressive spectrum sensing in CRNs and the main contributions are firstly reviewed in Sect. 4.1. In Sect. 4.2, the proposed robust compressive spectrum sensing working at a single CR user is presented. Section 4.3 gives the related simulation results. Additionally, the proposed robust sub-Nyquist spectrum sensing

Advanced Spectrum Sensing Techniques
2019Spectrum sensing plays an important role in cognitive radio networks. Based on the bandwidth considered for spectrum sensing, it can be classified into narrowband and wideband spectrum sensing. Traditional spectrum sensing methods are devised for narrow band as it focuses on narrow frequency a range that is the channel bandwidth is lesser than the ...

In cognitive radio systems, spectrum sensing is critical since it determines which kind of spectrum sharing schemes can be used. For example, in cognitive small cell networks, a large number of small cells with short transmission range can share the same spectrum band with a macro cell.
