查询词典 vector decomposition

Wavelet packet decomposition can decompose high-frequency part of signal. In order to obtain the energy rate index of each node this paper advances apply wavelet packet decomposition method to node response of pipe. And then use statistics method to analysis the energy rate index indicator of various nodes in pipe. Results show this method not only can detect the locations of damage in pipe, but also can get a preliminary study for quantify the damage degree damage of pipe.

A novel direction of arrival and polarization estimation of electromagnetic vector sensors mounted on the airframe is proposed based on biquaternion. The signal processing model for EM-sensor mounted on the airframe is made by biquaternion and then the eigenvalue decomposition of spectral matrix is obtained by means of the EVD of its quaternion adjoint matrix. The memory requirement for data is reduced, and more accurate estimation result is gotten by deducing the stronger orthogonality constraint between the sin- gal and noise subspaces on the field of biquaternion. The performance of the new algorithm is confirmed through numerical examples.
