Cooperative Spectrum Sensing Technique

摘要：

Cognitive 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 a brief introduction of the principle of cooperative sensing and discuss the cooperative sensing techniques in CRs. Simulation results show that cooperative sensing can improve the detection probability, improve the agility gain and thus help to improve the efficiency of spectrum.
