The Improved Signal Processing Method Based on Matrix Pencil Algorithm

This paper presents a new approach for signal processing method based on matrix pencil method, which is effective for exponential signal. The principle of matrix pencil method is based on the singular value decomposition (SVD), and the characteristics of the singular value are analysed for the high signal-to-noise (SNR). If reduced gradient of the singular value is less than the threshold value, the part of signal should be subdivision by wavelet packet, and then make it fusion with the result of matrix pencil method. The simulation results show that the improved signal processing method based on matrix pencil method has significant filtering effect and less restrictive applied field
