说明：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

说明：Spectrum sensing is a key technology in Cognitive Radio (CR). It provides the CR system with available vacant channels list by sensing the spectrum environment over a wide frequency band. However, local sensing by single node will be compromised if the sensing node experiences shadowing or fading effect. Cooperative spectrum sensing is derived to solve this problem
