Abstract
Abstract In this work, an analysis method based on fuzzy integral was proposed to analyze the features of digital broadcast bio-signals. First, the signal preemphasis and normalized was conducted. Second, the signal was decomposed into different subspaces with fuzzy integrals and features of each subspace were extracted. Then standardization, dimension reduction, and characteristics analysis are conducted on the eigenvectors of each digital broadcast subspace signal to realize the characteristic analysis of digital broadcast signals. The experiment results show that the response time of this method is between 20 and 30 min, the cost is less than 10,000 RMB, and the detection probability is greater than 97 %, which indicate that the proposed method can quickly and accurately analyze the characteristics of digital broadcast bio-signals.
