Xiaobo Zhu · Signal Processing · 2008
Alpha-stable distribution is a widely used noise distribution model.Therefore,this paper proposed a Rao statistical test method based on Alpha-stable distribution noise model,and presented the Rao decision rule of the detection of sine signal under the Al- pha-stable distribution noise environment.We present the detection performances of the proposed Rao test for different dispersionα,and compared with the Rao test that based on Gaussian assumption.Simulation results shows that the proposed Rao detector has good per- formance for the weak signal detection under the condition of Alpha-stable distribution noise environment,and it distinctively outperforms the Rao detector that based on Ganssian assumption.
