| Abstract: | According to the property of eigenvalue of sample covariance matrix, a new method is proposed to estimate the wideband or nonstationary signals number. By combining with the multiple hypothesis testing and bootstrap method, the new method does not need to know the signal type and any other statistic information. Theoretical analysis and simulation results illustrate the effectiveness of the method. |
