原始语种摘要: Spectrum sensing is one of the core functionality of a cognitive radio system. Accurate identification of primarysystem signal can prevent interference and provide maximum protection to licensed users. However, manychallenges associated with spectrum sensing still exist. Examples include shadowing, multipath fading of theprimary user signal, hidden primary user problem and many more. To circumvent the challenges faced by sensingdevice, the cooperative decision from participating devices has been proposed in the literature. In this paper, wesuggest a cooperative decision based on support vector machine (SVM) for spectrum sensing in vehicularcommunication environment to mitigate shadowing and multipath fading. Spectrum sensing can be formulated as apattern recognition problem with sensing...
