The Vector-bispectrum Based on Data Fusion and Its Application in the Fault Diagnosis
Lei Chen · Turbine Technology · 2006
A new analysis method,vector-bispectrum,is presented based on data fusion and bispectrum.The definition is defined,the estimation formula is derived and the properties are improved.The simulation and experiments demonstrate that this method is effective and accurate in Gaussian noise restraining and the fault diagnosis of common non-linear failure.
